Here are some tips that you may want to consider when designing your solution, especially a complete search solution, to bring it a better chance of passing the Time Limit. ### Tip 1: Filtering versus Generating Programs that contain lists of all candidate solutions and choose those that are correct (or remove the incorrect ones) are called "filters," e.g., the n-queens solver with O(n²) time complexity and the drastic attention to the VLSI. Lazy filter programs are sometimes useful. Programs that gradually build the solutions and immediately prune invalid partial solutions are called "generators," e.g., the improved n-queens solver with O(n²) time complexity. Usually, "generators" are more time-efficient. Generally, filters are easier to code but risk slow down. Do the math to see if a filter is good enough or if you need to create a generator. ### Tip 2: Prune Infeasible Search Space Early In generating solutions using recursive backtracking (see tip 1 above), we may encounter a partial solution that will never lead to a full solution. We can prune the search at easy-to-spot parts of the search space. For example, see the diagonal check in n-queens solutions. Suppose we have placed a queen at row 1, column 2 (row[2] = 1 for column 2) + 3 will result in a conflict if we attempt placing another queen at row[2] = 2 (row[2] = 2). Thus, pruning certain paths of partial solutions will never lead to a valid solution. This can prune the total solution paths at this juncture, concentrating on only valid positions of row[2] = {4, 5, 6, 7, 8}, thus saving overall runtime. ### Tip 3: Utilize Symmetries Some problems have symmetries and we should try to exploit symmetries to reduce execution time! In the n-queens problem, there are 92 solutions for the exam on any 12 queen (or function) and symmetries that are quite notable and less unwieldy in this problem. You can reduce computation time by arranging the 12 unique solutions and, if needed, generate the whole by mirroring and reflecting these 12 unique solutions. Example for: {7, 8, 3, 1, 5, 6, 2, 4} is the bottom-left reflection of Figure 11. ### Tip 4: Pre-Calculation a.k.a. Pre-Calculating Sometimes it is helpful to define tables or other data structures that enable the fastest possible retrieval of information you will need later in the program. This is called pre-computation, which can reduce memory/space for time. However, this technique can be hard to manage for those new programming constructs. Here’s an example that solves the problem above. Since we know there are 92 solutions for n queens problem, if we create a generator program [2] that lists all 92 permissible entries of the queens setup beforehand, we can write another for the solutions that merely utilizes all combinations of these beforehand information. ### Tip 5: Try Solving the Problem Backwards Surprisingly, some correct problems look far harder when they are solved "backwards" (from the idea defining ahead). Rather than actively working with a forward attack (from the more obvious angle), be ready to process the data in reverse other than the obvious. > It is said that every program is doing most of its task in only about 10% of the code—the critical code.

Then, proceed to the platform-specific design guide document, which in this current context is the **PC platform specification document**. You have to consult the concepts explained in the **TPM main specification**, parts 1–4, and the **TSS** document while reading the **PC platform specification document**—the dashed blue arrows in figure 13.3 mean "consult." You can download the **TCG Specification Architecture Overview** at [https://www.trustedcomputinggroup.org/specs/TSS](https://www.trustedcomputinggroup.org/specs/TSS), and the **TPM main specification**, parts 1–4, at [https://www.trustedcomputinggroup.org/specs/PCClient](https://www.trustedcomputinggroup.org/specs/PCClient). The **PC platform specification document** consists of several files; the relevant ones are: - **TCG PC Client-Specific Implementation Specification for Conventional BIOS** (as of the writing of this book, the latest version of this document is 1.20 final) - **PC Client TPM Interface Specification FAQ** Reading these documents will give you a glimpse of the concepts of trusted computing and some details about its implementation in PC architecture. Before moving forward, I'll explain a bit more about the fundamental concept of **trusted computing** that is covered by the TCG standards. The **TCG Specification Architecture Overview** defines trust as the "expectation that a device will behave in a particular manner for a specific purpose." The advanced features that exist in a trusted platform are protected capabilities, integrity measurement, and integrity reporting. The focus is on the integrity measurement feature because this feature relates directly to the BIOS. As per the **TCG Specification Architecture Overview**, integrity measurement is "the process of obtaining metrics of platform characteristics that affect the integrity (trustworthiness) of a platform; storing those metrics; and putting digests of those metrics in PCRs (platform configuration registers)." I'm not going to delve into this definition or the specifics about PCRs. Nonetheless, it's important to note that in the TCG standards for PC architecture, **core root of trust measurement (CRTM)** is synonymous with **BIOS boot block**. At this point, you have everything required to understand these concepts.

Here are the current LIS updates: - Initially, A[0] = 7, we have A = [7] - We can insert A[1] = 10 so that we have a longer LIS A = [7, 10] - We can insert A[2] = 8 and do not have a longer LIS A = [7, 8] - For A[3] = 6, it only extends A[0] so we have A = [6, 10] - For A[4] = 3, we can insert 3 into A as A = [3, 10] - For A[5] = 9, we can extend A[3] = 3 to have a longer LIS A = [3, 9] - For A[6] = 5, we can extend A[0] = 3 to be A = [3, 5] - For A[7] = 4, the longest subsequence does not change so it remains A = [3, 5] - For A[8] = 6, we can extend A[2] = 5 to A = [3, 6] This example shows the steps it takes to update the LIS; it's important as the steps can be longer and take the form of 6, 5, 4, 3, 1, 1 instead of just the longest size or length throughout the process. [Example code: Longest Non-Increasing Subsequences](https://github.com/UVA231/spc-chg/UVA231.java) ## 2. Max Sum Abbreviated problem statement of UVA 108 - Maximum Sum: Given an n x k (1 ≤ k ≤ 100) square matrix of integers, extract a submatrix with the maximum sum. ### Example: The 4 x 4 matrix (n = 4 in Table 3.3) below has a 3 x 2 sub-matrix with the lower-bound with maximum sum of 15 (1+5+9). There is also another 3 x 3 sub-matrix with larger sum. #### Table 3.3 UVA 108 - Maximum Sum | | | 1 | 2 | 3 | 4 | |---|---|---|---|---|---| | 1 | 1 | -127 | -127 | -127 | -127 | | 2 | 2 | -127 | 7 | | | | 3 | 3 | 1 | 0 | 0 | | | 4 | 4 | 2 | 0 | 0 | | Attacking this problem naïvely using brute force for a shown box does not work as it needs O(n³). For these reasons, we use O(n²) algorithms to solve. ```cpp maxSub = -1274100; // the lowest possible value for this problem for (int i = 0; i < n; i++) { for (int j = 0; j < m; j++) { // start at (0,0) for (int k = i; k < n; k++) { for ( int l = j; l < m; l++) { // answer is here } } } } ``` **The answer is here** Solutions: The naive brute-force DP solution is to explore smaller submatrices, and this would involve computing smaller submatrices in its and sums computation involves overlapping submatrices!

The two of you can debug it together while focusing on the WA code may be a good idea rather than having a great coding contest. 5. (c) The ICM: Problem 2. Ask your team members to scrutinize the printed output. This could be useful to look at another problem in attempt to solve TWO more test cases. Some of this code may have bugs being coded in less than 30 minutes. (then others can do this while your team mates can find the bug for the WA code by looking at the printed code). ``` Image Analysis: ## Image Analysis ### Localization and Attribution - **Image 1:** The entire content of the page. ### Object Detection and Classification - Contains **text** as the primary object. ### Text Analysis - **Extracted Text:** - Code snippet for problem-solving in programming context. - "Exercise 1.2.4" with instructions and scenarios addressing responses to coding problems. - Includes options (a), (b), (c), for different scenarios and responses. - **Content Significance:** - The text addresses coding challenges, specifically related to competitive programming scenarios. - It provides strategic responses to potential coding problem outcomes like WA (Wrong Answer) and TLE (Time Limit Exceeded). - Highlights the importance of coding efficiency and error resolution. ### Scene and Activity Analysis - **Scene:** - A page with text focusing on a programming exercise. - **Activities:** - Code review and strategy discussion for programming contests. ### Perspective and Composition - **Perspective:** - The document is presented in a straightforward, vertical layout typical for text documents. - **Composition:** - The text is organized into a code section and a problem exercise section, divided for clarity and focus. ### Contextual Significance - **Overall Message:** - Provides guidance on how to handle specific programming contest scenarios, emphasizing problem-solving strategies and teamwork. ### Text Analysis: Additional Aspects - **Ablaufprozesse (Process Flows):** - The text outlines processes for handling coding errors and contest scenarios. - **Prozessbeschreibungen (Process Descriptions):** - Detailed steps for addressing coding errors, prioritizing tasks, and collaborating with team members. - **Typen Bezeichnung (Type Designations):** - Types of responses to specific coding problems, like WA and TLE. #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 253 Context: ``` # INDEX © Steven & Felix - **UVa 00322** - Dungeon Master, 94 - **UVa 00354** - Frogger, 59 - **UVa 00436** - Oddities, 187 - **UVa 00683** - Goldbach's Conjecture, 134 - **UVa 00687** - Artificial Intelligence, 154 - **UVa 00688** - Balancing Bank Accounts, 16 - **UVa 00689** - The Thief, 24 - **UVa 00694** - Team Score, 26 - **UVa 00705** - Eratosthenes' Sieve, 23 - **UVa 00753** - Recursive Tree, 27 - **UVa 00654** - Heavy Cargo, 89 - **UVa 00658** - Havel, 120 - **UVa 00675** - Managing a Bunch of Buddies, 76 - **UVa 00678** - Bridge Hands, 5 - **UVa 00586** - Warships, 17 - **UVa 00602** - Drinking Coins, 68 - **UVa 00626** - Organize, 107 - **UVa 00631** - Piano Accompanist, 46 - **UVa 00665** - Risk, 40 - **UVa 00682** - Just the Facts, 26 - **UVa 00697** - Job, 63 - **UVa 00701** - Up-Digits, 35 - **UVa 00712** - The Small, 17 - **UVa 00713** - Always on the Run, 124 - **UVa 00714** - The Reckless Driver, 165 - **UVa 00762** - Prime Factors, 143 - **UVa 00763** - Archery, 61 - **UVa 00764** - Forwarding, 82 - **UVa 00767** - The BLAST!, 1 - **UVa 00781** - Are You There?, 121 - **UVa 00795** - Tiers, 154 - **UVa 00801** - Building Newspaper, 45 - **UVa 00802** - The Search for the Trees, 37 - **UVa 00804** - Counterclockwise, 211 - **UVa 00806** - Prime Number, 87 - **UVa 00810** - Helpmate, 43 - **UVa 00811** - Mapping the Routes, 82 - **UVa 00814** - So Little Time, 14 - **UVa 00816** - The A Team, 127 - **UVa 00819** - Number of Segments, 88 - **UVa 00824** - Subset Sum, 89 - **UVa 00825** - Simple Searches, 71 - **UVa 00832** - Game Evaluation, 154 - **UVa 00836** - Rerun, 134 - **UVa 00850** - Binary Search, 7 - **UVa 00862** - The Wall, 78 - **UVa 00863** - Passwords, 65 - **UVa 00864** - Vending Machines, 16 - **UVa 00865** - Pythagorean Triples, 128 - **UVa 00868** - Self Numbers, 101 - **UVa 00869** - Sort the List, 254 - **UVa 00870** - Defending, 30 - **UVa 00871** - The Largest, 146 - **UVa 00872** - Ledge, 14 - **UVa 00873** - Magic, 40 - **UVa 00874** - A Sorted Collection, 155 - **UVa 00875** - Pebble Counting, 72 - **UVa 00876** - Queue, 21 - **UVa 00877** - Scoring Discussion, 1 - **UVa 00878** - The Enigma, 22 - **UVa 00879** - Time Complexity, 118 - **UVa 00880** - Archaeologist's Dilemma, 7 - **UVa 00881** - The Ruler's Status, 43 - **UVa 00882** - Repeat, 45 - **UVa 00883** - The Field, 55 - **UVa 00884** - Lollipop Problems, 153 - **UVa 00885** - The Farmer's Dilemma, 78 - **UVa 00886** - Base Conversions, 26 - **UVa 00888** - Canonical Sequence, 114 - **UVa 00889** - Commandments of the Game, 134 - **UVa 00890** - The Astrologer, 155 - **UVa 00891** - One Ship Cheap, 64 - **UVa 00892** - Fibonacci Numbers, 129 ``` Image Analysis: I'm unable to display or browse attachments.

Produce this code loading skill by discussing a harder problem in UVA online judge where the runtime of the best solution is out of bounds. Slightly smaller variants of your accepted solution reduce the runtime differences. Adopt caching modification that gives you faster runtime. ### Tip 7: Use Better Data Structures & Algorithms :) No kidding. Using better data structures and algorithms always outperforms any optimization tips mentioned in Tips 1-6 above. If all else fails, abandon Complete Search approach. ### Remarks About Complete Search in Programming Contests If a problem is designated to be solvable by Complete Search, it will then be done iteratively or recursively using either a brute force or an exhaustive backtracking approach. Iterative approaches are used when one can derive the different conditions easily without retraining a variable to a certain counter and all cases can be checked, exploring all possible permutations of a small set. Recursion backtracking is useful when referring to the different states using some sort of recursive method to return to the base case, i.e., the specific desired solution. Another thing to note is the search space of a problem that is solvable with Complete Search is large; the recursive backtracking that pulls the data from the initial search space is particularly crucial. The best way to improve your Complete Search skills is to solve many problems solvable with Complete Search. We have categorized a list of such problems into four sub-categories below. Please attempt as many as possible, especially those that are highlighted as **must try**. ### Programming Examples Enabling Using Complete Search: 1. **Iterative:** 1. UVA 101: Ecological Badlands (try all possible combinations) 2. UVA 102: The Simple Problem (bruteforce map) 3. UVA 103: Stacking Boxes (try all possible permutations) 4. UVA 104: A Change in the Weather (try all available items) 5. UVA 105: Perfect Dice (try all) 2. **Recursive:** 1. UVA 106: The 3-d N Queens (brute-force backtracking) 2. UVA 107: The Seven Dwarfs (find seven) 3. UVA 108: Maximum Sum (find max sum from 0 to n) 4. UVA 109: The Ascent of Mt. Carmel (num and cost of pairs) 3. **Constraint Satisfaction:** 1. UVA 110: The Twin (find twin pairs) 4. **Combinatorial:** 1. UVA 111: Event Scheduling (gathering on certain dates) 2. UVA 112: Biology (patient with limited visits) 3. UVA 113: The Windy (find bucket of water) 4. UVA 114: Block Pairs (count all possible pairs) ### Footnotes: 1. The algorithm discussed emphasizes research, but note that it is merely a guideline. 2.

This text will help students in the future, as there will be many graph algorithms. However, we have learned the constraints that prevent ICPCs and OIs (usually) from just asking contestants to solve problems involving the pure form of these graph algorithms. Next, problems usually require contestants to combine two or more algorithms together. We consider some problems that have special attributes, e.g., BS and DP’s in the same problem, enabling the largest path in a directed acyclic graph (DAG). These hard forms of graph problems are discussed in Section 2. There are a lot of special graphs in the Standard Library. An extra complication is that it is not clear that Dynamic Programming (DP) is the way to benchmark for Max Flow. As these problems usually have difficult structures, the right mix for these types of graph problems may seem complex. For instance, we note that constants must satisfy the usage of the specific parameter for eliminating an algorithm for solving the Max Cardinality Bipartite Matching problem (MCBM). We examine this section that started with two different approaches: a slow method and a fast one using the regular Bipartite Graph. We do not have to worry with Bipartite graphs as it is still a good idea to utilize constants. The other general graph discussed in this chapter — the Debarrah Graph — does not have too many constraint problems involving it anyway. There are also other special graphs, but very rarely concerned them, e.g., Planar Graph, Complete Graph, and Root of graphs. When they appear, try to utilize their special properties to speed up your algorithms. Thus, this chapter is one of the essential links among various graph algorithms and graph problems that may be raised in ICPCs, mainly subset problems, Bipartite Matching, Satisfies Problems, etc. Lin Enderson algorithm for Min Cost Arborescence problem, Tarjan’s Offline function on Communicating Ancestors (Hungarian) algorithm, Edmondson’s Blossom Shrinking algorithm, and many more. If you want to increase your winning chance in ACM ICPC, please spend some time in required notes and if they arise, you can easily become the divisor of problems. Hard graphs are discussed later in the book. These notes have great special materials in the 100 syllables already covered in this chapter. --- There are **320 UVA (+30 others)** programming exercises discussed in this chapter. (Only 173 in the first edition, a **37% increase**.) There are **49 pages in this chapter.** (Only 31 in the first edition, a **40% increase**.) > **Interested readers are welcome to explore** Felik’s paper [12] that discusses maximum flow algorithms for large graphs of all sizes written and 10 billion edges.

If we have to nominate a chapter in this book that contestants have to really master, we will choose this one. The main source of the "Complete Search" material in this chapter is the USACO training gateway [2]. We adopt the name "Complete Search" rather than "Brute Force" as we believe that some "Complete Search" solutions can be clearer and more insightful, although it is complete. We define the term "Complete Search" as a self-reinforcing method. We will discuss some advanced search techniques later in Section 3.8, such as A* Search, Depth Limited Search (DLS), Iterative Deepening Search (IDS), and Iterative Deepening A* (IDA*). Divided and conquer paradigms is usually seen in the form of its popular algorithms: binary search and its variants, merge/split (merge sort), and data structures have array lists, heap, segment tree, etc. We will see more D&C later in Computational Geometry (Section 7.4). As for Greedy and Dynamic Programming (DP), potential techniques are always included in popular introductory texts, e.g., Introduction to Algorithms [3], Algorithm Design [2], Algorithm [4]. However, for those who want the programming difficulties and clarity of other techniques, especially the DP techniques, we include some references from Internet: "Dynamic algorithm tutorial" [1] and recent programming contests. In this book, we will revisit DP apart from one excursion: [First Ward's DP Algorithm (Section 6.7), DP (implied) DAG (Section 3.17), DP on Strings (Section 6.5), and more Advanced DPs (Section 5.4)]. However, for some real-life problems, especially those that are classified as NP-Complete [5], many of the approaches discussed so far will not work. For example, K-Satisfiability Problem with base O(N^5) complexity is known if s is big P's search (O(N^2) or P's complexity) to know if V is much larger than K. For such problems, people use heuristics or local search. Tabu Search [14], 3-SAT, Greedy Algorithm, Auto Cleanup Optimization, Beam Search, etc. These are 19 UVA (4 + 15 other) programming exercises discussed in this chapter. (Only 10 in the first edition, a 75% increase). There are 32 pages in this chapter. (Also 32 in the first edition, but some content have been reorganized to Chapter 4 and 8). Image Analysis: Here's a detailed analysis of the attached visual content based on the provided aspects: 1. **Localization and Attribution:** - **Image 1:** This is the only image on the page, located at the center. 2. **Text Analysis:** - The image is a scan of a page with the heading "Chapter Notes." - The main text discusses algorithms in ICPC and various search techniques, including A* search, Dijkstra's, and others related to self-reduction. - It references NP-complete problems and programming exercises, specifying 179 UVa exercises and 32 pages in the chapter. - Significance: It provides an overview of the algorithms covered in the chapter, along with context on exercise difficulty. 5. **Diagram and Chart Analysis:** - No diagrams or charts are present in this image. 10. **Contextual Significance:** - The text serves as a summary or notes for a chapter, likely in a textbook on computer algorithms. - It guides readers through the topics covered and gives an idea of the complexity level of exercises. 11. **Metadata Analysis:** - As a scan of a physical book page, there is no digital metadata available for analysis. 12. **Graph and Trend Analysis:** - There are no graphs included in this image. - **Prozessbeschreibungen (Process Descriptions):** - The text describes processes related to problem-solving approaches in competitive programming, such as reductions and complexity considerations. - **Trend and Interpretation:** - It indicates a focus on complex problem-solving techniques pertinent to competitions like ICPC. Overall, the image is a textual summary page from a chapter in a book about algorithms, providing insight into the topics and exercises covered. #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 86 Context: # 3.6 Chapter Notes Many problems in ICPC or IEO require one or combination (see Sections 3.2) of these problem-solving paradigms. If we have to summarize a chapter in this book that constitutes how to really master, we will discuss this one. The main source of the "Compute Search" material in this chapter is the USACO training gateway [2]. We adopt the term "Compute Search" rather than "Brute Force" as we believe that some "Compute Search" solution can be more exact and strong, although it is complete. We refer to the term "Brute Force" as a bit discrediting. We will discuss some advanced search techniques later in Section 3.8, A* Search, Depth Limited Search (DLS), Iterative Deepening Search (IDS), and Iterative Deepening A* (IDA*). **Divide and Conquer** paradigm is usually used in the form of its popular algorithms: binary search and its variants, merge/sort (merge sort), and data structures such as heaps, segment trees, etc. We will see more D&C later in Computational Geometry (Section 7.4). **Dynamic Programming (DP)** techniques/implementations are always included in popular algorithm textbooks, see Introduction to Algorithms [3], Algorithm Design [4], and others. However, to keep you with the growing difficulties and clarity of these techniques, especially the DP techniques, we include some references from Introductory Techniques [1] and several programming contests. In this book, we will revisit DP for an interesting focus: [First Wassily’s DP algorithm](Section 6.7), P.A (implied) DAG (Section 3.17), D.R String (Section 6.5), and some Advanced DP (Section 5.4). However, for some NP-complete problems, especially those that are classified as NP-Complete [5], many of the approaches discussed do not work. For example, K-Satisfiability Problem which has O(N^5) complexity is known to be if b is big then P(b, N^k) < 2^N complexity is too low if N is much larger than k. For such problems, people use heuristics or local search. Tabu Search [14], 14, Genetic Algorithms, Ant Colony Optimization, Branch Search, etc. --- These are 19 UVA (4 + 15 others) programming exercises discussed in this chapter. (Only 10 in the first edition, a 75% increase.) There are 32 pages in this chapter. (Also 32 in the first edition, but some content have been reorganized to Chapter 4 and 8.)

You receive a WA response for a very easy problem. What should you do? a. Abandon this problem and go another. (not ok, your team will lose out.) b. Improve the performance of your solution. (not useful.) c. Create tricky test cases and find the bug. (the most logical answer.) d. (In ICPC) Ask another coder in your team to re-do this problem. (this is a logical answer. this can work although your team will lose precious penalty time.) 2. You receive a TLE response for your O(n^2) solution. However, maximum N is just 100. What should you do? a. Abandon this problem and go another. (not ok, your team will lose out.) b. Improve the performance of your solution. (not ok, we should have got TLE with an O(n) algorithm if N ≤ 200.) c. Create test cases and find the bug. (this is the answer; maybe your program is accidentally trapped in an infinite loop in some test cases.) 3. Follow up question (see question 2 above): What if maximum N is 10,000? If N > 200, you have no choice but to improve the performance of the algorithm or use a faster algorithm. 4. You receive an RTE response. Your code runs OK on your machine. What should you do? a. Begin debugging. (individual codes like this can help you point to the potential issues such as your code might be using undefined variables or infinite recursion. Doing this before focusing on the WA code may be a good practice rather than investigating other AC codes.) 5. (c) The ICPC problem is tricky. Ask your team members to scrutinize the printed output and look for variations. a.

Then follow the arrows using recursive backtracking. Exercise 6.5.1.3 The DP solution only needs to refer to previous rows in the table (“space saving trick”). Thus, it should only create two rows to store the current row and the previous row. The space policy is `O(n)` (columns), but it’s the string length when looking at strings of size `2` (in each row) that gives the greatest concern (free memory). The time complexity of this solution is `O(n^2)` and `O(n)` for this space overhead. Exercise 6.5.1.4 Simply concentrate along the main diagonal with width `k`. We can speed up Needleman-Wunsch’s algorithm to `O(nk)` by doing this. Exercise 6.5.3 The solution is not shown. It involves Kadane’s algorithm again (see maximum sum problem in Section 5.2.3). ### Exercise 6.5.2.1: ‘spies’ Exercise 6.5.2.1 To reduce the match to `0`, insert and delete = negative infinity. However, this solution is not distinct, as we can simply use an `O(n^2)` algorithm to scan both string `1` and string `2` and count how many characters are different. Exercise 6.5.2.2 This is a straightforward solution. The reduction to LIS is not shown. Draw it and see how it reduces problem into LIS. Exercise 6.6.1: Straightforward. Solution is not shown. Exercise 6.6.2.1 ‘C’ is found, CAT is not. Exercise 6.6.3.1 ‘EVE’. Details not shown. Exercise 6.6.3.2 ‘EVE’. Details not shown. Exercise 6.6.4: The answer is the same as Exercise 6.6.3.2 which is ‘ACATTA’. Exercise 6.6.5.1 The answer is the same as Exercise 6.6.3.1 which is ‘EVE’. ### Chapter 7 Exercise 7.2.1.1: (3.0) Exercise 7.2.1.2: (3.0, 4.0) Exercise 7.2.2: The program `y = mx + c` cannot handle all the cases. Vertical lines have 'infinite' gradient; also in this equation. If we use this line equation, we have to treat lines separately and condition that defines the probability of acceptance. Fortunately, this can be resolved by using the former equation by `y = c` when `x = 0`. Exercise 7.2.2: `x + 3*y + 2 = 0`. If you use the line `y = mx + c` equation, you will leave `2 = 2*0 + 3*(-2)`. Exercise 7.2.4: Given points `(x1, y1)` and `(x2, y2)`, the slope can be calculated with `m = (y2 - y1)/(x2 - x1)`. Subsequently, the `y`-intercept can be computed from the equation by substitution of the values of a point (either one) and the line gradient form. The code will look like this: ```c struct line2 { double m, c; }; // another way to represent a line ``` Image Analysis: Certainly!

Linker script can control every aspect of the linking process, such as the relocation of the compilation result, the executable file format, and the executable entry point. Linker script is a powerful tool when combined with various GNU binutils. Figure 2.2 shows that it's possible to do **separate compilation**, i.e., compile some assembly language source code and then combine the object file result with the C language compilation object file result by using LD linker. There are two routes to building a pure machine code or executable binary if you are using GCC: 1. Source code compilation ➔ Object file ➔ LD linker ➔ Executable binary 2. Source code compilation ➔ Object file ➔ LD linker ➔ Object file ➔ Objcopy ➔ Executable binary This section deals with the second route. I explain the linker script that's used to build the experimental PCI expansion ROM in part 3 of this book. It's a simple linker script. Thus, it's good for learning purposes. Start with the basic structure of a linker script. The most common linker script layout is shown in Figure 3.3. ### Figure 3.3 Linker script file layout | Output File Format | |-------------------------------| | Target Machine Architecture | | Executable Code Entry Point | | Other Definitions ... | | Sections Definition | Linker script is just an ordinary plain text file. However, it conforms to certain syntax dictated by LD linker and mostly uses the layout shown in Figure 3.3. Consider the makefile and the linker script used in chapter 7 as an example. You have to review the makefile with the linker script because they are tightly coupled. 1. The format of an executable file is operating system dependent. 2. GNU binutils is an abbreviation for GNU binary utilities, the applications that come with GCC for binary manipulation purposes. 3. Execution environment is the processor operating mode. For example, in a 32-bit x86-compatible processor, there are two major operating modes, i.e., 16-bit real mode and 32-bit protected mode.

TPM Software Stack (TSS) Document Figure 1.3 Steps in comprehending TCG standards implementation in PC architecture Figure 1.3 shows that the first document you need to read is the **TCG Specification Architecture Overview**. Then, proceed to the platform-specific design guide document, which in the current context is the PC platform specification document. You have to consult the concepts explained in the TPM main specification, parts 1–4, and the TSS document while reading the PC platform specification document—the dashed blue arrows in figure 1.3 mean "consult." You can download the **TCG Specification Architecture Overview** at [trustedcomputinggroup.org/specs/TPM](https://www.trustedcomputinggroup.org/specs/TPM). The TSS document is available for download at [trustedcomputinggroup.org/specs/TSS](https://www.trustedcomputinggroup.org/specs/TSS), and the PC platform specification document is available for download at [trustedcomputinggroup.org/specs/PCClient](https://www.trustedcomputinggroup.org/specs/PCClient). The PC platform specification document consists of several files; the relevant ones are **TCG PC Client-Specific Implementation Specification for Conventional BIOS** (as of the writing of this book, the latest version of this document is 1.20 final) and **PC Client TPM Interface Specification FAQ**. Reading these documents will give you a glimpse of the concepts of trusted computing and some details about its implementation in PC architecture. Moving forward, I'll explain a bit more about the fundamental concept of trusted computing that is covered by the TCG standards. The **TCG Specification Architecture Overview** defines **trust** as "the expectation that a device will behave in a particular manner for a specific purpose." The advanced features that exist in a trusted platform are protected capabilities, integrity measurement, and integrity reporting. The focus is on the integrity measurement feature because this feature relates directly to the BIOS. As per the **TCG Specification Architecture Overview**, integrity measurement is "the process of obtaining metrics of platform characteristics that affect the integrity (trustworthiness) of a platform; storing those metrics; and putting digests of those metrics in PCRs [platform configuration registers]." I’m not going to delve into this definition or the specifics about PCRs. Nonetheless, it's important to note that in the TCG standards for PC architecture, **core root of trust measurement (CRTM)** is synonymous with **BIOS root block**. At this point, you have all the necessary context. Image Analysis: ### Image Analysis #### 1.

This can be done by simultaneously constructing the target and its full sub-matrix as shown below for sample matrix (see Table 3.3) and also matrix (see Table 3.4). ```c scan( *arr, *max ) { for (int i = 0; i < row; i++) { // the dimension of input square matrix scan(arr[i], max); } } ``` First, we want to have sum of any sub-matrix (i, j) from (0, 0) to (i, j). Suppose we want to have sum of `(0, 0)` to `(3, 3)`. We split the sum matrix into sections and apply the formula `sum(3, 3) = sum(3, 3) - sum(0, 3) - sum(3, 0) + sum(0, 0)` as highlighted in Table 3.3. With this (DP) formulation, this problem can be solved in O(N^2). For the largest test case when N = 100, this is fast enough. ```c result = -1 * INT_MAX; // the lowest possible value for this problem for (int i = 0; i < k; i++) { for (int j = 0; j < k; j++) { // start coordinates int sub_sum = 0; // get sub matrix this sums all from (0, 0) to (i, j) for (int x = 0; x <= i; x++) { for (int y = 0; y <= j; y++) { sub_sum += arr[x][y]; // summation } } // the answer is here result = max(result, sub_sum); } } ``` #### Example code: `sub.cpp`, `sub.java`, `cpp/Ex1/Part1.dos` Not every range produces Sequence or Polynomial Time as in Section 2.3.3 or 2.3.4 Problems where the input data is static. This problem is usually solvable with DP technique. It is also worth applying consensus techniques for this problem in terms of structure using the bottom-up technique utilizing recursion with matrix and loops in the first place. For given recursive top-down solutions, you may reference structures in (P vs NP). Actually, this works best when it uses a certain dynamic programming style of this problem. Can you figure out how to do this? ### Example Problem Given a Knapsack (Subset Sum) problem. Discuss (N, W) items with its own value `v[i]` and weight `w[i]` (i = 0, …, n-1), and a maximum knapsack size `W`, compute the maximum value of the items that you can carry. If one can carry it, then the result can be in state forms. The solution from Exercise 3.5.2.2 to find maximum item in 1D array applied here. #### Challenge Problem: You can refer to structure from (P, NP). Assume that the data is static. ### 3.1 Knapsack (Subset Sum) This problem is also known as the **Subset Sum Problem**. Given a set of integers `A = {a1, a2, ... , an}` and a number `S`, find a subset of `A` whose sum is equal to `S`. The Subset Sum problem is solvable with Greedy algorithms. ``` Image Analysis: ## Image Analysis ### Localization and Attribution - **Image 1:** - Located at the center of the page. - Contains both text and code blocks. ### Object Detection and Classification - **Image 1:** - **Objects Identified:** - Text blocks. - Code snippets. - **Classification:** - Text is mostly academic, discussing dynamic programming. - Code segments involve programming logic and calculations. ### Scene and Activity Analysis - **Image 1:** - **Scene Description:** - The scene is an academic text page focused on computational algorithms. - **Activities:** - Explanation of dynamic programming concepts. - Demonstration through code examples. ### Text Analysis - **Image 1:** - **Extracted Text:** - Discusses dynamic programming with matrix transformations. - Details specific code for summing sub-matrices. - References exercises and example problems. - **Significance:** - Provides insights into solving dynamic programming problems using code. - Aimed at students or professionals studying algorithms. ### Diagram and Chart Analysis - **Image 1:** - Contains no explicit diagrams or charts, but includes code snippets. ### Contextual Significance - **Image 1:** - **Context:** - Part of a larger academic text, likely a textbook or educational material. - Aims to explain and teach dynamic programming concepts. - **Contribution:** - Enhances understanding by combining theory with practical code examples. - Supports learning through visual representation of algorithm logic. ### Process Descriptions - **Image 1:** - Describes the transformation of matrices in terms of dynamic programming. - Includes algorithmic steps to calculate sums of sub-matrices. ### Trend and Interpretation - **Image 1:** - **Trends Identified:** - Focus on efficient computation through dynamic programming. - Emphasis on coding solutions for algorithmic problems. - **Interpretation:** - Highlights the intersection of computer science theory and practical application. - Represents a methodical approach to problem-solving in programming. ### Tables - **Image 1:** - Contains no explicit tables, only inline text and code.

However, we are aware that there are still many more mathematics problems and algorithms that have not been discussed in this chapter. Here, we list some points to remember and topics that you may be interested in exploring further by reading other books, see [3], investigating mathematical topics in [http://projecteuler.net/](http://projecteuler.net/) [8]. - There are many more combinatorial problems and formulas that are not yet discussed: - Burnside's lemma - Cayley's Formula - Derangements - Stirling Numbers, etc. For a much faster prime testing function than the one presented here, consider the stochastic deterministic Miller-Rabin's algorithm—which can be made deterministic for specific contexts with a known maximum input size. In this chapter, we have seen a quite effective algorithm for finding rational integer factors of an algebraic and lots of useful functions. For a faster integer factorization, one can use the Pollard's rho algorithm that uses random cycles to detect nontrivial factors. Brent's cycle finding method, however, if the integer to be factored is a prime number, then it is still slow. That is the key idea of modern cryptographic techniques. - There are other theorems, hypotheses, and conjectures that cannot be discussed here, e.g.: - Carmichael's function - Riemann's hypothesis - Goldbach's conjecture - Ramat's Little Theorem - Twin prime conjecture - Chinese Remainder Theorem - Sprague-Grundy Theorem, etc. To compute the solution of a system of linear equations, one can use techniques like Gaussian elimination. As you can see, there are many topics about mathematics. This is not surprising since various mathematical problems have been investigated by people since many hundreds of years ago. Some of the entries found in this chapter may differ from each other, and not all 1 or 2 will actually appear in a problem set. To dive into IPC, it is good to have at least one thesis statement in your IPC team in order to have those 1 or 2 mathematics problems solved. Mathematical proof is crucial to point out constants. Although the amount of topics to be mastered is smaller, you must still recognize some form of mathematical insights. Note that (Computer) Geometry is part of Mathematics, but since we have a special chapter for that, we reserve the discussions about geometry problems in Chapter 7. There are 25% IVA (+10 others) programming exercises discussed in this chapter. (Only 175 in the first edition, a 67% increase). There are 29 pages in this chapter. (Only 17 in the first edition, a 71% increase). Image Analysis: 1. **Localization and Attribution:** - **Image 1:** The entire page represents one image. 4. **Text Analysis:** - The text appears to be a section from a book titled "Chapter Notes." It discusses the expansion of chapter content compared to previous editions, focusing on mathematics problems, algorithms, and additional topics not thoroughly covered in the chapter itself. - The main points include: - Mention of combinatorics problems and formulas such as Burnside’s lemma, Cayley’s Formula, and Stirling Numbers. - Discussion about integer factorization techniques and cryptography. - Reference to well-known conjectures and theorems like Carmichael’s function and the Goldbach conjecture. - Instructions on solving systems of linear equations using techniques like Gaussian elimination. - Statistical note on the increased number of exercises and pages in programming discussions. There are now 29 pages in this chapter, a significant increase from earlier editions. - The notes aim to guide readers towards other resources and topics, indicating an educational or instructional context. 10. **Contextual Significance:** - The image contributes to the overall message of the book by providing additional resources and insights into mathematical topics that enrich the reader's understanding.

For multiple test cases, you should include two identical sample test cases consecutively. Both must output the same known correct results. This is to check whether you have forgotten to initialize sample variables, which will be easily identified if the test instance produces the correct output but the second does not. 2. Your test cases must include edge cases. Increase the input size incrementally up to the maximum possible stated in problem description. Sometimes your program works for small input sizes, but behaves wrongly (or slowly) when input sizes increase. Check for overflow, out of bounds, etc. if that happens. 3. You cannot just duplicate test cases to increase the number of test cases (space), this is not a valid response. Check carefully and justify your cases. 4. You need to include the tricky corner cases. Think like the problem setter! Identify cases that are ‘hidden’ in the problem description. Some sample entries: \( N = 0, N = 1, N = \text{maximum value allowed in problem description} \), etc. Think of the worst possible input for your algorithm. 5. Do not assume the input will always be nicely formatted if the problem description does not say so (especially for real-world problems). Try to handle extreme cases (space, time) as your program may break. Always check your code is able to read in the values correctly (e.g. if there are empty entries or similar). Finally, generate large random test cases to see if your code continues to run fast and give reasonably correct outputs; the constraints is there to verify time - but this is only tested with your corner cases during the run time. However, after all these steps, you may still get non-PC responses. In ICPC, you and your team can actually see the judge's response to determine your next actions. With more experience in such contexts, you will be able to make better judgments. See the next exercise: ### Exercise 1.2.4: Structural Judging (Mainly in ICPC settings) This is not relevant to 101. 1. You receive a WA response for a very easy problem.

String processing is common in the research field of **bioinformatics**. However, as the strings that transfer data deal with unusually complex bio, efficient data structures and algorithms were necessary. Some of these problems are presented as contest problems in ICPC. By mastering the content of this chapter, ICPC contestants will have a better chance at tackling these string processing problems. String processing has also appeared in IOI, but usually in the role of reading and writing data structures or requiring the use of various I/O restrictions. Additionally, the input and output formats are usually quite simple. The problems that tend to come in string processing are similar to solving the well-known programming problems. IOI tasks that require string processing are usually all solvable using the problem solving paradigms mentioned in Chapter 5. It is instructive for I/O contestants to learn string algorithms in this chapter except Section 5.4 that is primarily concerned with DP. However, we observe that it may be advantageous for IOI contestants to learn some of the more advanced material outside of their syllabus. ## 6.2 Basic String Processing Skills We begin this chapter by listing several basic string processing skills that every competitive programmer must have. In this section, we provide a series of mini-tasks that you should solve one after another without asking. You can use your favorite programming language (C, C++, or Java). Try your best to keep up with the sub-tasks, using default input/output formats for testing. 1. Given a string that only includes characters [A-Za-z], digits [0-9], space, and period (`.`), write a program that reads this file line by line and encounters a long string `t`. When two lines are combined, give some examples such that the last word of the previous line is separated from the first of the current line. There can be up to 30 such occurrences per given input. Also, be sure to follow standard input and output formats. Note: The sample input file `file.txt` is shown on the next page: After question (1) and before task 2. 2.

Here are some tips that you may want to consider when designing your solution, especially a complete search solution, to give it a better chance of passing the Time Limit. ## Tip 1: Filtering versus Generating Programs that examine lists of all candidate solutions and choose those that are correct (or remove the incorrect ones) can yield "filters," e.g., the naive-sequence solver with \( O(n^2) \) time complexity and the drastic optimization of the Two's Tables. Similarly, other programs are written as "generators." Programs that start with table solutions and immediately prune invalid partial solutions are called "generators"; e.g., the improved sequence solver with \( O(n) \) complexity plus assigned checks. Usually, 'generating' programs are more efficient. Generally, filters are easier to code but miss fewer. Do the math to see if a filter is good enough or if you need to create a generator. ## Tip 2: Prune Infeasible Search Space Early In generating solutions using recursive backtracking (see Tip 1 above), we may encounter a partial solution that will never lead to a full solution. We can prune the search at the appropriate parts of the search space. For example, see the diagram about the k-squares solution above. Suppose we have placed a queen at row \( 2 \) and, by placing another queen at row \( 2 \) (i.e., row \( 2 \) + 3), it will lead to an invalid situation and placing another queen at row \( 2 \) will cause a conflict. Therefore, any of these partial solutions will never lead to a valid solution. Thus, we can prune the search for partial solutions at this juncture, concentrating on only valid positions of row \( [4, 5, 6, 7, 8] \), thus saving overall runtime. ## Tip 3: Utilize Symmetries Some combinatorial problems are structured such that we can exploit symmetries to reduce execution time! In the k-squares problem, there are \( 20 \) solutions that differ only in \( 12 \) unique (or fundamental) configurations that are rotational and have various symmetries in this problem. You can reduce your programming complexity by utilizing these unique features and, if needed, generate the results by mirroring and reflecting the \( 12 \) unique solutions. Example row: \( [7, 3, 1, 6, 2, 4] \) is the horizontal reflection of Figure 1. ## Tip 4: Pre-Calculation a.k.a. Pre-Calculation Sometimes it is helpful to pre-calculate other data structures that enable the fastest possible methods to solve problems later. This is true for numerous areas of the program. This is called Pre-computation, as it creates more runtime space for time. However, this technique can help lead to faster programming. Since there are \( 27 \) unique boards, let’s consider \( [28] \) as the ideal board with \( 12 \) unique solutions. Suppose we create a generator program (which takes some runtime!) that is dynamic and functional. By doing so, we can ensure our task has much less overhead and can find the correct pathways to solutions in \( O(n) \) (very fast). ## Tip 5: Solve the Problem Backwards Surprisingly, some combinatorial problems look far easier when they are solved "backwards" (from the idea directly sought) than when they are solved using a forward attack (from the more obvious angle). Be ready to process the data in the direction that is not as obvious. * "It is said that every program is doing most of its work to solve just about 80% of the code - the critical code." Image Analysis: I'm unable to directly analyze the content of the image you've provided. However, I can guide you on how to perform a thorough analysis based on the outlined criteria. Below is a structured way to approach analyzing a document page like the one displayed in your image: 1. **Localization and Attribution:** - Identify and number the images on the page. Since this is a document page with text, you may treat sections or diagrams (if any) as individual images. 2. **Text Analysis:** - Extract the text content. The document seems to include various textual tips related to programming strategies, such as Filtering Versus Generating, Avoiding Infeasible Search Space, Utilizing Symmetries, Pre-Computations, and Solving Problems Backwards. - Each tip provides strategies for solving computational problems more efficiently, targeting issues like time complexity, managing search space, and using symmetry. 3. **Process Descriptions (Prozessbeschreibungen):** - The text describes processes for generating solutions, managing search space, and pre-computing solutions to make problem-solving faster. 4. **Object Detection and Classification:** - Identify any diagrams or figures mentioned in the text. For example, references to problem structures or example sequences should be noted. 5. **Scene and Activity Analysis:** - The page illustrates logical and computational strategies rather than physical scenes or activities. 6. **Diagrams and Chart Analysis:** - Analyze any diagrams mentioned, such as those describing solution sequences or calculation strategies (e.g., reflection and rotation in symmetries). 7. **Perspective and Composition:** - Review the layout of the text to understand how instructions and examples are structured, aiding in comprehension. 8. **Color Analysis and Anomalies:** - If physical color or design elements are present, they typically guide the reader’s eye or emphasize sections (this particular image of the document page does not appear to have color). 9. **Contextual Significance:** - This page likely contributes to a larger work on programming problem-solving approaches, indicating a methodical approach to efficient algorithm design. 10. **Metadata Analysis:** - Check for any metadata in the document file regarding authorship, creation date, or edition, if needed. 11. **Typen Bezeichnung (Type Designations):** - Identify any types or categories presented in the text, such as specific algorithm types or problem-solving categories. By following these criteria, you can perform a comprehensive analysis of similar document pages. #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 59 Context: # 3.2 COMPLETE SEARCH Stein & Figs This tip is best shown using an example: UVA 10308 - Rat Attack. Imagine a 2D array (up to 1024 x 1024) containing rats. There are `N` rats at coordinates (x, y) that should be treated as the number of rats killed in square from (x, y) to (x + d, y + d) is minimal. This is the part of the sample given in Figure 1. The first step is to tackle this problem trivially: By bombarding each of the 1024 cells and see which one is the most effective. For each bombed cell (x, y), we need to do `O(d^2)` rates to count the number of rats killed within the square bombed radius. The worst-case time when the array has size `1024` and `d` is at least `1024` is `O(N^2)`. This is TLE! The second option to tackle this problem is to create an array `rat[k][l]` for each rat populating the bounds (r1, c1) to (r2, c2) for all `(k, l)`. This way each rat in the ranges (r1 - 1, c1 - 1) to (r2 - 1, c2 - 1) is stored in a 0-indexed coordinate. This preprocessing takes `O(N^2)` operations. Then, to determine the number of rats in the rectangular area (r1, c1) to (r2, c2) for any rats killed, which can be done in `O(1)` operations. This backwards approach only requires `O(2000 * 5000)` = `10^6` times operations for the worst case (N = 2000, d = 50). Figure 2: UVA 10308 [28] ## Tip 6: Optimizing Your Source Code There are many tricks that can serve to optimize your code. Understanding computer hardware, especially I/O, memory, and cache behavior, can help you design a better program. Some examples: 1. Use the faster C/C++ `cin`/`cout` rather than `scanf`/`printf` in C. For Java, prefer `BufferedReader` instead of `Scanner`. However, if speed is crucial, stick to `BufferedInputStream`. 2. Use the `opord(log n)` query that is cache-friendly quickest (C++ STL algorithm: `sort`). 3. Access a 2D array in a row-major fashion (row by row) rather than column by column. 4. Bit manipulation can often be more efficient than the use of arrays (see the highlighted section of Book in Section 22.1). If we need more than 64 bits, use `C++ STL bitset` rather than `std::vector`. 5. Use lower-level structure management where possible. For example, an array with size that equals to the maximum size instead of using resizable vectors like `std::vector`. 6. In C++, prefer using the faster `array` rather than `std::vector` for small-sized elements. 7. Be careful with string manipulation in Java: `C++ STL string`, `Java raw` must be careful with `String` manipulations as Java `String` objects are immutable. Optimizations can be gained this way. 8. For Java, prefer the faster `ArrayList` rather than `Java Vector` as thread safety is not used in competitive programming.

Here are some tips that you may want to consider when designing your solution, especially a complete search solution, to give it a longer chance of passing the Time Limit. ### Tip 1: Filtering versus Generating Programs that contain lists (of all) candidate solutions and choose those that are correct (or remove the incorrect ones) are called "filters," e.g., the n-queens solver with `N` time complexity and the drastic anomaly of the Tool 725. Usually, filter programs are written first. Programs that gradually build candidates and immediately prune invalid partial solutions are called "generators," e.g., the n-queens solver with `S` complexity plus assigned checks. Usually, generating programs are written afterward. Generally, filters are easier to code but more tedious. Do the math to see if a filter is good enough or if you need to create a generator. ### Tip 2: Prune Infeasible Search Space Early In generating solutions using recursive backtracking (see Tip 1 above), we may encounter a partial solution that will never lead to a full solution. We can prune the search at those special parts of the search space. For example, as the diagonal check in n-queens solves the puzzle, suppose we have placed a queen at row 2 (`row[2] = 2`). Then placing another queen at `row[2] = 1` or `row[2] = 3` will create a conflict. Thus, we can prune this path. Continuing down all these partial solutions will never lead to a valid solution. Thus, we can prune the overall solution right at this juncture, concentrating on only valid positions of `row[2] = [4, 5, 6, 7, 8]`, thus saving overall runtime. ### Tip 3: Utilize Symmetries Some problems have symmetries and we should try to exploit symmetries to reduce execution time! In the n-queens problem, there are `2N` solutions for the same `N` by considering rotational and reflective transformations. This problem can be solved without generating all `2N` solutions. Example: for `N = 7`, `S = {7, 3, 1, 6, 2, 4}` is the binary representation of the board configuration. ### Tip 4: Pre-Calculation a.k.a. Pre-Calculation Sometimes it is helpful to pre-calibrate other data structures that enable the fastest possible runtime, especially if you’re using them as part of the program finish. This could be pre-computable or static numbers that reduce memory/space for time. However, this technique can get trickier due to the inherent programming complexities. ### Tip 5: Solving the Problem Backwards Surprisingly, some contest problems look far harder when they are viewed "backwards" (from the final destination) than when they are solved using a straightforward forward (from the more obvious angle). Be ready to process the data in reverse and think carefully about the correct paths for efficient solutions. *It is said that every program is doing most of its task to ask about 10% of the code—the critical code.* ``` Image Analysis: Here is a detailed analysis based on the provided image content: ### Localization and Attribution: - **Image 1**: The text and diagrams are located on a text-heavy page, formatted in columns. ### Object Detection and Classification: - **Image 1**: Features mainly text blocks and a small flowchart related to solving problems in programming. ### Scene and Activity Analysis: - **Image 1**: The scene comprises a structured document page likely from a book or academic resource.

Many programming problems involving game theory are classified as Zero-Sum Games—a mathematical way of saying that if one player wins, then the other player loses. For example, a game of the Two-Line Game (i.e., UVA 1011, Class, various number theory games (e.g., UVA 514, 1063, 1067, 1101, and others (UVA 1016, 1044, 1131) are games with two players playing alternately (usually perfectly) and there can only be one winner. ### 5.8.1 Decision Tree The common question asked in programming problems related to game theory is whether the starting player has a winning strategy, and how both players are doing Perfect Play. That is, each player always chooses the move that maximizes their available options. One question to consider is whether to explore the Decision Tree of the game (also called the game tree or search tree). If a game is finite, meaning there are a limited number of states, a complete search might be reasonable to consider. However, if the game is infinite or too large, heuristic approaches might be more suitable. To diagram a state of the game, the root node is the position of the starting player, and the edges are the possible moves. The current state is evaluated to see if it is winning for the starter. Other options may be explored, but if that node is not feasible, the player may choose a node closer to the Minimax strategy. #### Programming Exercises related to Cycle-Philips 1.

This trend will help students in the future, as there will be many graph algorithms. However, we have to warn the students that recent ICPCs and OI usually do not just ask contestants to solve problems involving the pure form of these graph algorithms. New problems usually require contestants to combine two or more algorithms together to solve the same problem, encompassing the largest path in DAG with supported data structures, using DP, and graphs. This chapter also has problems based on the Dijkstra and Bellman-Ford's algorithms to demonstrate. The problem solving contest path and DP which led to Dijkstra's algorithm is an essential part of graph theory. To transition the graph into DAG, we need to establish a proper way. We also discuss the general way of approaching the Max Cardinality Bipartite Matching (MCBM) problem. We have also mentioned the section that may require help to MCBM with regard to graph construction. There’s also the section that mentions Bipartite Graph and how it can still lead to produce valid outputs. The other graph-related topics discussed in this chapter — the Hungarian Graph — do not have too many concrete problems involving it directly. There are other algorithms related to graph, but they may expand, for instance, Planar Graph, Complete Graph Ax, Prefix of Paths, etc. When they appear, try to utilize their special properties to speed up your algorithms. Thus, it is crucial that students aim not only to understand graph algorithms, but also how they interconnect, like shortest paths, Kahn's Algorithm, Prim's, Dijkstra's, Edmonds' Algorithm for Min Cost Arborescence Problem, Tarjan's Offline Minimum Cut, and Kőnig-Kuhn (Hungarian) algorithm. If you want to increase your standing chance in ACM ICPC finals, please spend some time to review these rigorous methods and if they can actually become the driver of problems. Standard graph problems are not limited to queries found in this book.

References to these libraries are available online at [openclassroom.com](https://www.openclassroom.com) and [java.com](https://www.java.com/java/references/api). Note that although these reference websites are usually given in programming courses, we suggest that you try to master the syntax of the most common library operations at the same time during the actual courses! An exception to this practice is the [highlighting of Behold](http://behold.com). This unusual data structure provides a way for data structures and algorithm classes, but it is quite important for computer programmers as it plays a significant role in exactness. This data structure appears in [USP Tech](https://usptech.s3.amazonaws.com) in Section 3.2.1, DP (Text Section 3.2.2), DP + bucket (Section 6.1). All of these tech data structures can lead to records to look back: "Ticker's Delight" tells students the manipulation. External references for data structures mentioned in Section 2.3 are as follows: For Graph data structures, see [References 2][3] for Trin Find, [References 4][5] for Workbench, [6][7] for Segregation 3D and other specific data structures, see [8]. By working through these materials and experiences, you can develop some simple models to master those structures. There are also five data structure designs in this book. The triage-based data structures (Suffix, Trie, Tree/Array) in Section 6.1. Yet, there are still many other data structures that you must consider. If you want to delve into programming, please study the data structures beyond what you present in this book. For example, AVL Tree, Red Black Tree, or Splay Tree are useful for certain coded problems where you need to implement and make sense of them directly [9]. Interval Trees which is similar to Segment Tree, could help (see Part IV, Section 3). Notice that some of the data structures shown in this book have the spirit of Divide and Conquer (discussed in Section 3). There are 117 UIs (4+ 7 others) programming exercises discussed in this chapter. (Only 48 in the first edition, a 1995 version). There are 16 pages in this chapter. (Only 12 in the first edition, a 505th remove). --- ## Profile of Data Structure Inventors **Reydolf Bayor Lankh (1930)** has been Professor (emeritus) of Informatics at the Technical University of Munich. He invented the Red-Black (RB) Tree which is typically used in C++ STL API, see [1]. **Eugene Alexandrov-Vasiliev (Boros 1923)** is a Soviet mathematician and computer scientist, along with Reydolf Mihailovich Lankh, he invented the AVL tree in 1962. **Eyablinski Nicholai Lansk (1927)** was a Soviet mathematician. The name AVL tree is the abbreviation of the two inventors: Adelson-Velskii and Landis himself. **Peter M. Fawcett** is a Honorary Associate Professor in the University of Auckland. He invented Binary Search Tree and contributed programming concepts of efficient yet easy to implement data structures by his inclusion in the 101 syllables [10]. ``` Image Analysis: Certainly!

Then, proceed to the platform-specific design guide document, which in the current context is the PC platform specification document. You have to consult the concepts explained in the TCG main specification, parts 1–4, and the TSS document while reading the PC platform specification document—the dashed blue arrows in Figure 13.3 mean "consult." You can download the [TCG Specification Architecture Overview](https://www.trustedcomputinggroup.org/specs/TSS). The TSS document is available for download at [https://www.trustedcomputinggroup.org/specs/TSS](https://www.trustedcomputinggroup.org/specs/TSS), and the PC platform specification document is available for download at [https://www.trustedcomputinggroup.org/specs/PCCLIENT](https://www.trustedcomputinggroup.org/specs/PCCLIENT). The PC platform specification document consists of several files; the relevant ones are: 1. TCG PC Client–Specific Implementation Specification for Conventional BIOS (as of the writing of this book, the latest version of this document is 1.20 Final) 2. PC Client TPM Interface Specification FAQ. Reading these documents will give you a glimpse of the concepts of trusted computing and some details about its implementation in PC architecture. Before moving forward, I'll explain a bit more about the fundamental concept of trusted computing that is covered by the TCG standards. The TCG Specification Architecture Overview defines trust as the "expectation that a device will behave in a particular manner for a specific purpose." The advanced features that exist in a trusted platform are protected capabilities, integrity measurement, and integrity reporting. The focus is on the integrity measurement feature because this feature relates directly to the BIOS. As per the TCG Specification Architecture Overview, integrity measurement is "the process of obtaining metrics of platform characteristics that affect the integrity (untrustworthiness) of a platform; storing those metrics; and putting digests of those metrics in PCRs [platform configuration registers]." I'm not going to delve into this definition or the specifics about PCRs. Nonetheless, it's important to note that in the TCG standards for PC architecture, core root of trust measurement (CRTM) is synonymous with BIOS boot block. At this point, you have...

If we have to dominate a chapter in this book that contestants have to really master, we will choose this one. The main source of the "Complete Search" material in this chapter is the USACO training gateway [2]. We adopt the term "Complete Search" rather than "Brute Force" as we believe that some Complete Search solutions can be clearer and more efficient, although it is complete. We refer to the term "Complete Search" as a self-certification. We will discuss some advanced search techniques later in Section 3.8, A* Search, Depth Limited Search (DLS), Iterative Deepening Search (IDS), and Branch-and-Bound (A*). Divided and conquer paradigms is usually seen in the form of its popular algorithms: binary search and its variants, merge/sort (they sort), and data structures having linear, leap, segment trees, etc. We will see more D&C later in Computational Geometry (Section 7.4). Also, Greedy and Dynamic Programming (DP) techniques/exercises are always included in popular algorithm textbooks, see Introduction to Algorithms [5], Algorithm Design [2], Algorithm [4]. However, to keep pace with the growing difficulties and diversity of these techniques, especially the DP techniques, we include new references from Internet, "Dynamic Programming" [1], and recent programming contests. In this book, we will revisit DP again for a few occasions: First, Warshall's DP algorithm (Section 4.7), DP on (implied) DAG (Section 3.17), DP on String (Section 6.5), and some Max Flow (Section 5.4). However, for some NP-complete problems, especially those that are classified as NP-Complete [3], many of the approaches discussed so far will not work. For example, a Knapsack Problem with loose O(N*S) complexity is known if S is big. Yet problems such as O(N^2 * 2^S) complexity is too slow if N is much larger than K. For such problems, people use heuristics or local search. Tabu Search [14], Genetic Algorithms, Ant Colony Optimization, Beam Search, etc. --- These are 19 UVA (41 + 0.75%) programming exercises discussed in this chapter.

Note that the "extension" code might need to be placed in memory above the 1-MB barrier because you don't have enough free space below that barrier. In that case, you have to use an x86 voodoo-mode trick in your injected POST routine code to branch to the "extension" code. 1. Integrate the module to the BIOS binary with Chrom, using the `/other` switch. Nevertheless, pay attention to the LZH header's `segment:offset`. This element must be handled like other compressed BIOS components that are not the system BIOS and its extension. > Note that Chrom can compress new BIOS modules and integrate them with the original binary by using the `/other` command line option. By using this option, you can place the starting address of the decompressed version of your module upon booting. Actually, this switch does nothing to the additional BIOS module other than create the right destination `segment:offset` address in the LZH header of the compressed version of the module that you add into the BIOS. Thus, you have to decompress the module by calling the BIOS decompression routine in your injected POST jump table routine. From section 5.1.3.4, you know that the `segment:offset` that I'm referring to in this context is fake, because the destination address of the decompression is always segment 4000h for an extension component and various BIOS uses some of the bits as per the rule explained in that section. Figure 12.10 is a screenshot of an older version of Chrom showing the hint to use the `/other` option. ![Figure 12.10 Chrom /other option explanation](https://www.rebels havenforum.com/disbush/ultimates.php?sub=opt_topic&f=52&t=000004) 7 Various versions of Chrom can be downloaded from [Rebels Haven Forum](http://www.rebelsavenforum.com/disbush/ultimates.php?sub=opt_topic&f=52&t=000004). 8 Read section 5.1.3.4 about decompression of extension BIOS components.

Then, proceed to the platform-specific design guide document, which in the current context is the PC platform specification document. You have to consult the concepts explained in the TCG main specification, parts 1–4, and the TSS document while reading the PC platform specification document—the dashed blue arrows in Figure 13.3 mean "consult." You can download the [TCG Specification Architecture Overview](https://www.trustedcomputinggroup.org/specs/TPM), TCG PC main specification, parts 1–4, and the TSS document at [trustedcomputinggroup.org/specs/TSS](https://www.trustedcomputinggroup.org/specs/TSS). The PC platform specification document is available for download at [trustedcomputinggroup.org/specs/PCCLIENT](https://www.trustedcomputinggroup.org/specs/PCCLIENT). The PC platform specification document consists of several files; the relevant ones are: - TCG PC Client–Specific Implementation Specification for Conventional BIOS (as of the writing of this book, the latest version of this document is 1.20 Final) - PC Client TPM Interface Specification FAQ Reading these documents will give you a glimpse of the concepts of trusted computing and some details about its implementation in PC architecture. Before moving forward, I'll explain a bit more about the fundamental concept of **trusted computing** that is covered by the TCG standards. The *TCG Specification Architecture Overview* defines trust as the "expectation that a device will behave in a particular manner for a specific purpose." The advanced features that exist in a trusted platform are protected capabilities, integrity measurement, and integrity reporting. The focus is on the integrity measurement feature because this feature relates directly to the BIOS. As per the *TCG Specification Architecture Overview*, integrity measurement is "the process of obtaining metrics of platform characteristics that affect the integrity (trustworthiness) of a platform; storing those metrics; and putting digests of those metrics in PCRs [platform configuration registers]." I'm not going to delve into this definition or the specifics about PCRs. Nonetheless, it's important to note that in the TCG standards for PC architecture, core root of trust measurement (CRTM) is synonymous with BIOS boot block.

There are dedicated directories for the flash model that it supports, namely, `nics`, `bios`, `ct`, and `ide`. `Nics` contains source code related to PCI network interface cards that `cfLFlasher` supports. `Bios` contains source code for a motherboard based on the SiS 630 chipset. `Ct` contains source code for the proprietary `cfLFlasher` hardware. `Ide` contains files for the IDE `cfLFlasher` interface. The directory named `modules` is empty at first. It will be filled by `cfLFlasher`'s LKM when you have finished compiling the code. The directory named `build2.6` contains the makefile for kernel 2.6. Finally, the directory named `flash` contains the source code for the flash ROM chip supported by `cfLFlasher`. `CfLFlasher` source code is well-structured, and it's easy to understand. For PCI NIC, you start to learn the `cfLFlasher` source code by studying the NIC support files in the `nics` directory and then proceed to the `flash` directory to learn about the flash ROM-related routines. The PCI NIC support file provides routines needed to access the flash ROM onboard, and the flash ROM support file provides the specific write, erase, and read routine for the corresponding flash ROM chip.

Every nth person is to be executed. Only the last remaining person will be saved, and this person is said to be the one who has “survived.” The smallest version of this problem can be solved with plain brute force. The larger ones require better solutions. ## Problems related to Palindrome or Anagram There are two classic problems: - **Palindrome** is a word (or actually a sequence) that can be read the same way in either direction. The simplest strategy to check if a word is a palindrome is to loop from the first character to the middle and check if the first matches the last, the second matches the second last, and so on. Example: `A man, a plan, a canal, Panama!` is a palindrome. - **Anagram** is a rearrangement of letters of a word (or phrase) to get another word (or phrase) using all the original letters. The common strategy to think of two words as anagrams is to sort the letters of the words and compare the sorted letters. Example: word = `anagram`, sorted word = `aaagmnr`. ## Interesting Real Life Problems This is one of the most interesting categories of problems in UA I’ve done in my whole life. We believe that the real life with programming is far more interesting for those who are not computer scientists, but for those who do want programs to solve real-world problems in an arithmetic way. Who knows; you may also learn some new interesting knowledge from the problem description! ## Ad Hoc problems involving Time Date, time, calendar, etc. All these are also real life problems. As usual, people usually want extra functionality when doing with real life problems. Some of these problems will be much more complicated. The solution for this problem is to simply follow/understand the problem description carefully. ## Just Ask Even after efforts to sub-categorize the Ad Hoc problems, there are still many others that are not fitting into the previous specific sub-category. The problem is that these problems are such anomalies. The solution is for each problem to simply follow the problem description carefully. ## Ad Hoc Problems in Other Chapters There are many other Ad Hoc problems which spread to other chapters, especially because they require more knowledge on top of basic programming skills. - Ad Hoc problems involving the usage of basic linear data structures, especially arrays, are listed in Section 2.1. - Ad Hoc problems involving mathematical computations are listed in Section 5.2. - Ad Hoc problems involving processing of strings are listed in Section 6.3. - Ad Hoc problems involving basic geometry skills are listed in Section 7.2.

Here are some steps that can be followed: - Initially, let \(A = [7, 9]\). - We can insert \(K = 10\) at \(A[0]\) so that we have a longer LIS as \(A = [7, 10]\). - Next, we can insert \(K = 5\) at \(A[0]\), but this won’t yield a longer LIS as our current LIS remains \(A = [7, 10]\). - For \(K = 3\), we can replace \(A[0]\) with \(A = [3, 10]\). - We can insert \(K = 2\) at \(A[0]\) to give us \(A = [2, 10]\). - For \(K = 8\), we can insert \(A[1]\) so that \(A = [2, 8]\). - Finally, for \(K = 1\), we can only insert at \(A[0]\) resulting in \(A = [1, 10]\). This example illustrates the initial steps in building the LIS, where each step is important as the tree can be longer than the previous longest increasing subsequence. > Example code: [Longest Non-Increasing Subsequence](https://github.com/UWCS/UVA231.java) ## 2. Max Sum Abbreviated problem statement of UVA 108 - Maximum Sum: Given an \(n \times k (1 \leq k \leq 50)\) square matrix of integers, extract a submatrix with the maximum sum. Example: The 4 x 4 matrix can be seen in Table 3.3 below as a 3 x 2 sub-matrix with the lower-left with maximum sum of 15 (i.e., the sum from 1, 5, 6, 7, 11, 2). | - | 1 | 2 | 3 | 4 | |-------|-------|-------|-------|-------| | **1** | - | - | - | - | | **2** | - | 1 | 3 | 4 | | **3** | 2 | 5 | 6 | 1 | | **4** | 7 | 11 | 3 | 2 | #### Code Snippet ```cpp maxSum = -127; // the lowest possible value for this problem for (int i = 0; i < n; i++) { for (int j = 0; j < m; j++) { // set each j for (int k = 0; k < n; k++) { // loop over rows for (int l = 0; l < m; l++) { // loop over columns // your logic here } } } } // the answer is here ``` ### Solution This approach will involve solving the initial problem using a DP approach. The DP can find the maximum sum, and hence smaller sub-matrices in \(O(n^3)\) and will involve computations involving overlapping sub-matrices!

Given that \( AP = PB \), \( AP \) is perpendicular to \( PB \), \( A \) is \( (2, 3) \), and \( B \) is \( (-3, -2) \), find the coordinates of \( P \). 62. The mid point of the hypotenuse of a right triangle is equidistant from the three vertices. This theorem, familiar from elementary geometry, makes no mention of axes. We therefore choose the most convenient axis, which is, in this case, the line joining \( A(0, 0) \) and \( B(0, 0) \), and the foot of \( M \) and the distances referenced in the exercise. 63. In any triangle \( ABC \) the line joining the mid points of \( AB \) and \( AC \) is parallel to \( BC \) and is equal to \( \frac{1}{2} BC \). The triangle may be regarded as given by the coordinates of the points. 64. Using oblique axes, prove from this figure that the diagonals of a parallelogram bisect each other. In proving this property from geometry by analytical geometry, it is convenient to use oblique axes as shown by the figure. Thus the diagonals have the same mid point. 65. The lines joining in succession the mid points of the sides of any quadrilateral form a parallelogram. 66. Using rectangular axes as shown below: If we denote \( O(0,0) \), we prove that the diagonals of \( g \) and \( h \) bisect each other. 67. The diagonals of a rhombus are perpendicular to each other. Since we have not studied the slope of a line \( l \) with respect to oblique axes, we have not included rectangular axes for this case. We may use the figure of \( K \), making \( O \) equal to \( O(0,0) \). Assuming that the coordinates of \( g \) and \( h \) are the coordinates of \( P \) and \( R \): 68. The vertices of a triangle are \( A(0, 0) \), \( B(4, 5) \), and \( C(6, -1) \). If \( H \) divides \( AB \) in the ratio \( 3:1 \), and \( P \) is a point on \( AC \) such that the area of triangle \( APM \) is half the area of \( ABC \), in what ratio does \( P \) divide \( AC \)?

The assembler must be able to work with the original binary, in particular reading bytes from it and replacing bytes in the original binary. 2. The assembler must be able to produce a final executable13 binary file that combines both the injected code and the original binary file. Among all assemblers that I've come across, only FASM that meets both of the preceding requirements. That's why I'm using FASM to work with the template.

For multiple input test cases, you should include two identical sample test cases consecutively. Both must output the same correct results. This is to ensure that you have forgotten to initialize some variables, which will be easily identified if the first instance produces the incorrect output but the second does not. 2. Your test cases must include large cases. Increase the input size incrementally up to the maximum possible stated in problem description. Sometimes your program needs for small input sizes, but behaves wrongly (or slowly) when input size increases. Check correctness, out of bounds, etc. if that happens. 3. Your test cases must include the tricky corner cases. Think like the problem setter! Identify cases that are the ‘hidden’ in the problem description. Some typical corner cases: \( N = 0 \), \( N = 1 \), \( N \) as maximum values which appear in the problem description, etc. Think of the worst possible input for your algorithm. 4. Do not assume that input will always be nicely formatted if the problem description does not say so (especially for early white problems). Try submitting a few weird test cases (spaces, tabs, etc.) even if your problem states that input will be clean to see if it will handle unexpected edges correctly. 5. Finally, generate large random test cases to see if your code continues to run fast and gives reasonably correct outputs. Random correctness is hard to verify here—it’s best to verify that your code runs within the time limits. However, after all these steps, you may still get non-Judge responses. In ICPC, you and your team can actually see the judge's response to determine your next action. With more experience in such contexts, you will be able to make better judgments. See the next exercises: ### Exercise 1.2.4: Stadium Judging (Mostly in ICPC setting. This is not relevant to 100.) 1. You receive a WA response for a very easy problem. What should you do? - (a) Abandon this problem and do another. - (b) Investigate the performance of your solution (optimize the code or use a better algorithm). - (c) Create test cases and find the bug. - (d) In teams contest: Ask another coder on your team to re-do this problem. 2. You receive a TLE response for an easy problem. However, maximum \( N \) is just 100. What should you do? - (a) Abandon this problem and do another. - (b) Investigate the performance of your solution (optimize the code or use better algorithm). - (c) Try to debug test cases and find the bug. 3. You encounter a RE response. Your code runs OK on your machine. What should you do? - (a) Abandon the problem with WA code, switch to that other problem in attempt to solve some more problems. - (b) (In ICPC): Print the WA code. Ask two other team members to scrutinize the code and repeat to see if they can find other problems in attempt to solve for more problems. Image Analysis: Certainly!

However, we are aware that there are still many more mathematics problems and algorithms that have been discussed in this chapter. Here, we list some points to promote related topics that you may be interested in exploring further for reading number theory books, see [3], investigating mathematical topics in [http://projecteuler.net/](http://projecteuler.net/) [8]. - There are many more combinatorial problems and formulas that are not discussed: - Burnside's lemma, - Cayley's Formula, - Derangements, - Stirling Numbers, etc. For a faster and easier testing function than the one presented here, consider the non-deterministic Miller-Rabin's algorithm—which can be made deterministic for context with certainty at a known maximum input size \( n \). In this chapter, we have seen a quite effective method for finding roots: factoring out an polynomial and its various functions. For a faster integer factorization, one can use the Pollard's rho algorithm that uses random cycles to determine the Brent's cycle finding method. However, if the intent is to detect a larger prime number, then this is still slow. That is the key idea of modern cryptographic techniques. - There are other theorems, hypotheses, and conjectures that cannot be discussed here, e.g., - Carmichael's function, - Riemann's hypothesis, - Goldbach's conjecture, - Fermat's Little Theorem, - twin prime conjecture, - Chinese Remainder Theorem, - Sprague-Grundy Theorem, etc. To compute the solution of a system of linear equations, one can use techniques like Gaussian elimination. As you can see, there are many topics about mathematics. This is not surprising since various mathematical problems have been investigated by people since many hundreds of years ago. Some of the results in this chapter may either serve as a starting point or merely as a problem set. To delve into IPC, it is good to have at least one mathematical problem to solve with IPC team in order to have those 2 mathematicians problems solved. Mathematical proofs can sometimes require some form of mathematical insight. Note that [Computational Geometry](#) is part of Mathematics, but since we have a special chapter for that, we reserve the discussions about geometry problems in Chapter 7. There are 25% VBA (+10 others) programming exercises discussed in this chapter. (Only 175 in the first edition, a 67% increase). There are 29 pages in this chapter. (Only 17 in the first edition, a 71% increase). Image Analysis: Certainly!

Here, we present two ways to construct a Suffix Array given a string T[0..n-1]. The first one is very simple, as shown below: ```cpp #include #include #include using namespace std; #define MAX_N 1010 // first approach: O(n*log n) char T[MAX_N]; // this naive SA construction cannot go beyond 1000 characters in MAX_N bool cmp(int a, int b) { return strcmp(T + a, T + b) < 0; } // compare suffixes int main() { int n = (int) (strlen(T)); // Read and immediately capture its length for (int i = 0; i < n; ++i) suffix[i] = i; // initial SA: 0, 1, 2, ..., n-1 sort(suffix, suffix + n, cmp); // sort: O(n*log n) for (int i = 0; i < n; ++i) printf("%d\t", suffix[i]); // print return 0; } ``` When performing on T = "AGGTACCA", the simple code above sorts all suffixes with string comparison. Here's produces the correct Suffix Array (S.A) = [7, 0, 3, 5, 1, 4, 2, 6]. However, this is generally inefficient on larger strings. An efficient construction will reduce the number of two (possibly) overlapping comparisons and replace the string with integers of each rank instead. (Note that the rank corresponds to the suffix's order.) A better way consists of Suffix Array that sorts the existing strings (partial inverses) of the suffixes directly. The new rank will replace the previous one corresponding to the current lexicographical order. This changes the discussion in [Table 6.1](#Table_6.1). | Initial ranks RA[i] = T[i] | Suffix Array SA[i] | Reference | Table 6.1 | |---------------------|---------------------|------------|----------| | ASCII | | | | | A: 0, G: 6, T: 3, C: 5 | | | | | S[A]= 1; S[G]= 7; S[T]= 2; S[C]= 5; | | | | | | | | | ## Table 6.1: Left/Right: Before/After Sorting; i = 1; Initial Sorted Order Appears * Initial ranks RA[i] = [1, 5, 2, 6, 1, 0, 3][Table 6.1]. * Initially, RA[i] stores the rank of suffix SA[i] = [0, 1, 2, 3, 4, 5, 6, 7]. Initially, T = "AGGTACCA" gives it exactly 8 symbols. * Example: T = "AGGTACCA" = 5 * together with the adequate ranks. * Suffix array SA[i] with the maximum suffix will be now Table 6.1, respectively: | Initial ranks RA[i] | Suffix Array SA[i] | Suffix | |---------------------|---------------------|--------| | A: 0, G: 6, T: 3, C: 5| 7, 0, 3, 5, 1, 4, 2, 6 | "AGGTACCA" | Image Analysis: 1. **Localization and Attribution:** - **Image 1:** The entire page contains a mix of text, code, and a table. 2. **Object Detection and Classification:** - **Image 1:** - Objects detected include text blocks, code snippets, and a table. - The table is classified as a graphical representation of data about suffix arrays. 3. **Scene and Activity Analysis:** - **Image 1:** - The scene involves technical content discussing suffix arrays in computer programming.

The materials from A/P Ken's lecture notes have since evolved from these initial notes into the current complex programming skills. The section about basic string processing skills (Section 6.2) and the KMP string processing problems are born from our experience with string-related problems and techniques. The number of programming exercises requested here is about three quarters of all the string processing problems discussed this chapter. We are aware that these are the typical ICPC problems; we intend to point out programming decisions to increase your programming skills. Due to some personal requests, we have decided to include a section on the String Matching problem (Section 6.4). We discussed the famous Knuth-Morris-Pratt (KMP) algorithm. The KMP implementation will be useful for you later to modify basic string matching routines if you still need fast performance. We believe KMP is fast enough for certain contexts. The practical implementation of Suffix Arrays (Section 6.6) is inspired mainly from the Suffix Array construction with the help of existing string processing problems. We would also like to mention other string matching algorithms such as those discussed in Bajaj-Karpe, Rabin-Karp, Aho-Corasick's, Finite State Automaton, etc. Interested readers are welcome to explore them. We have exposed the discussion of the famous String Alignment (Edit Distance) problem and its related Longest Common Subsequence problem in Section 6.5. There are several interesting exercises that discuss the variations of these two problems. These are 117 (V1 + 12 others) programming exercises discussed in this chapter. - **(only 14 in the first edition, a 18% increase).** - There are 24 pages in this chapter. - **(only 10 in the first edition, a 10% increase).** Image Analysis: ### Analysis of the Visual Content #### Localization and Attribution - **Image 1**: The page is the only image available. #### Text Analysis - **Image 1 Text Content**: - **Title and Headings**: "6.7 Chapter Notes" - **Main Text**: The text discusses the evolution and implementation of string alignment and processing skills in programming.

Then follow the arrows using recursive backtracking. Exercise 6.5.1.3 The DP solution only need to preserve pointers so it can utilize the ‘space saving trick’ for O(1) memory. This is true under the assumption that we can access the previous row. The drawback of this approach, is that any other space saving trick that is not well be unable to reconstruct the solution. So, if the actual solution is needed, we cannot use the space saving trick. Exercise 6.5.1.4 Simply concentrate along the main diagonal with width d. We can speed up Needleman-Wunsch’s algorithm to O(n) by doing this. Exercise 6.5.1.5 This result is not shown. It involves Kadane's algorithm again (see maximum sum problem in Section 5.2.3). Exercise 6.5.2.1 **Splice** Exercise 6.5.2.2 Let n be the length of m – 0, m-1 → insert and delete → negative infinity. However, this solution is not distinct, so we can simply use an O(n^2,m) algorithm to scan both string 1 and string 2 and count how many characters are different. Exercise 6.5.2.3 (See Exercise 6.5.1) solution. The reduction to LIS is not shown. Draw it and see how to reduce the problem into LIS. Exercise 6.6.1 Straightforward. Solution is not shown. Exercise 6.6.2.1 'C' is found. CAT is not. Exercise 6.6.3.1 'EVE'. Detail is not shown. Exercise 6.6.3.2 'EVE'. Detail is not shown. Exercise 6.6.4 'EVE'. Detail not shown. Exercise 6.6.5 The answer is the same as Exercise 6.6.3.2 which is 'ACCTAA'. Exercise 6.6.6.1 The answer is the same as Exercise 6.6.3.3 which is 'EVEN'. # Chapter 7 Exercise 7.1.1 3.0 Exercise 7.1.2 (3.0, 4.0) Exercise 7.1.3 The equation y = mx + c cannot handle all the cases. Vertical lines have ‘infinite’ gradient/ slope in this equation. If we use this line equation, we have to handle lines separately, and the formula becomes the probability of acceptance. Fortunately, this can be resolved by using the other line equation y = ax + b = 0. Exercise 7.2.2 x + 3y + 2 = 0 // if you use the y = mx + c line equation, you will leave x = -2/3 Exercise 7.2.4 Given points (p1) and (p2), the gap can be calculated with m = (y2 - y1)/(x2 - x1). Subsequently the y-intercept can be computed from the equation by substitution of the values of a point (either one) and the line gradient m. The code will look like this: ```c struct line2 { double m, c; }; // another way to represent a line ``` Image Analysis: Here's a detailed analysis of the attached visual content: 1. **Localization and Attribution:** - **Text Page:** The content appears to be from a textbook or instructional document. 2. **Text Analysis:** - **Text Content:** - The text lists exercises from sections 6.5.1.2 to 6.6.5.2 and includes a section labeled Chapter 7. - Exercises have different problem descriptions, often mentioning algorithms and mathematical equations. - **Significance:** - The exercises focus on algorithm design and mathematical problem-solving, likely aimed at students or professionals in computer science or mathematics. 3. **Contextual Significance:** - **Overall Message:** - The document provides exercises for understanding specific concepts in algorithms and problem-solving.

String processing is common in the research field of algorithms. However, as the strings that programmers deal with are usually extremely big, efficient data structures and algorithms are necessary. Some of these problems are presented as contest problems in ICPC. By mastering the content of this chapter, ICPC contestants will have a better chance at tackling these string processing problems. String processing has also appeared in IOI, but usually in the role of input and output data structures or varying size variable [sic] restrictions. Additionally, the input and output formats are usually quite tricky. These problems tend to catch the unprepared contestant off guard, especially when combined with some other problem solving paradigms mentioned in Chapter 5. It is difficult for most contestants to solve string-algorithm tasks in this chapter except Section 6.5 about string matching with DP. However, we believe that it may be advantageous for IOI contestants to learn some of the more advanced materials outside of their syllabus. ## 6.2 Basic String Processing Skills We begin this chapter by listing several basic string processing skills that every competitive programmer must have. In this section, we provide a series of mini-tasks that you should solve one after another without asking. You can use your favorite programming language (C, C++, or Java). Try your best to come up with the subtask, use default initialization, and be tactful in your solution. If you have come up with the simplest solution (e.g., bubble sort), then you can also try some of the more complicated ones (or even your own implementations). 1. Given a string that only consists of alphabetic characters [A-Za-z], digits [0-9], space, and period ('.'), write a program to read that file line by line until you encounter a line that starts with the pattern "end". 1. Concatenate (combine) each line into a long string T. When two lines are combined, give some whitespace such that the last word of the previous line is separated from the first of the current line. There can be up to 30 of any of your implementations that you may perform. 2. Note the sample input file `file.txt` is shown on the next page: After question 1(d) and before task 2.
