Image Analysis: 

I'm unable to analyze images directly. However, I can help guide you on how to approach analyzing such a page.

For an index page like this, here’s how you can analyze it based on the aspects you provided:

1. **Localization and Attribution:**
    - Typically, a single page will be treated as one image.

2. **Text Analysis:**
    - Detect and extract any text: The page is an index listing topics and page numbers.
    - Analyze the content: It categorizes topics with labels like "LA 3901 - Editor, 173" which signifies the topic 'Editor' is on page 173.

3. **Diagram and Chart Analysis:**
    - Not applicable as this is a text-only page.

4. **Product Analysis:**
    - There are no products depicted on an index page.

5. **Anomaly Detection:**
    - No anomalies are typically expected in an index listing.

6. **Color Analysis:**
    - Printed documents often use a simple color scheme, mostly black text on a white background.

7. **Perspective and Composition:**
    - The perspective is a typical flat, printed page. The composition is a structured list format.

8. **Contextual Significance:**
    - This page serves as a directory to quickly locate topics within a larger document.

9. **Metadata Analysis:**
    - Metadata specific to the document such as creation date or author may be available but isn’t visible directly from the page image.

10. **Graph and Trend Analysis:**
    - Not applicable as there are no graphs.

11. **Ablaufprozesse (Process Flows):**
    - Not applicable on an index page.

# 6.2 BASIC STRING PROCESSING SKILLS
### Steven & Felix

1. (a) Do you know how to store a string in your favorite programming language?
   (b) How to read a given text input line by line?
   (c) How to concatenate (combine) two strings into a larger one?
   (d) How to check if a string starts with `......` to stop reading input?

   I love CS2333 Competitive Programming. I also love Algorithm.

   > Note: You must stop after reading this line as it starts with 7 dots. After the first input block, there will be one loooooooooooong line...

2. Suppose we have our given string `T`. We want to check if another string can be found in it. Report all the indexes where `Pappa` is found (if it can be found in `T`). For example, if `T = "I love CS2333 Competitive Programming. I also love Algorithm" and `P = "love"`, the output should be the character `i` at index `23` (as part of `I love`). If `P` is `love`, then the output is `[23]`.

   a. How to find the first occurrence of a substring in a string (if any)?
   b. Do we need to implement a string matching algorithm like Knuth-Morris-Pratt (KMP) algorithm discussed in Section 6.4, or can we just use built-in functions?

3. Suppose we want to access simple analysis of the characters in `T` and also to transform each character into 10 binary numbers. The required analysis asks: How many digits, vowels, and consonants (other lower/upper case alphabets that are not vowels) are there in `T`? Can we access that (i.e., where is the length of any)?

4. Next, we want to break this string into tokens (words) and store them into an array (which could be a list). For this task, the delimiters of these tokens are spaces and punctuation marks (such as commas and periods). For the example string `T`, after breaking, we will have these tokens: `['I', 'love', 'CS2333', 'Competitive', 'Programming', 'I', 'also', 'love', 'Algorithm']`.

   a. How to store an array of strings?

5. Next, after storing the array, we want to find the frequency of each word. That is, we want to know which tokens contain `I`, `love`, `CS2333`, `‘1`, `‘1`, `‘love`, ‘programming`, ‘I’, ‘also`, ‘love`, ‘algorithm`.

   a. Which data structure best supports this word frequency counting problem?

6. The given list has one more item like the one used in our common dictionary. The length of this list has been constrained. Count how many characters are there in the last item?

   a. How to read a string when we do not know its length in advance?

   > **Note**: This is a text similar like the one used in our common dictionary.

---

*We can use the alternating path algorithm to compute the MCBM (see Section 4.7).*  
*The DP for the Juggling N Billiards Game implies that we can solve DP. The second DP evaluates the effect on the tree for all juggling paths leading from there.*  
*But first, we have to build the DMM by using Monte Carlo algorithms from the roots of SCG.*  
*Finally, create primes from the 2D segment and binary search.*

## 3.2 COMPLETE SEARCH
### Steven & Felix

You may want to tweak the "critical code" of your program first instead of painfully reducing the problem with a faster algorithm—which may not be trivial to design. 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.*

Context: # Getting Started: The Ad Hoc Problems

## The Josephus-type problems
The Josephus problem is a classic problem where there are people numbered from 1, 2, …, n, standing in a circle. 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.

Context: ## 3.2 COMPLETE SEARCH :smiley: Steven & Felix

Browse the literature of reference books [6](#) to find more information on how to speed up your code. 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. Get assistance in maximizing solution instances through a '1 to n' ratio; if it sounds good to you, we do not need BFS.

Context: # 3.2 COMPLETE SEARCH  
**© Steven & Felix**

You may want to tweak the "critical code" of your program first instead of painfully reducing the problem with a faster algorithm - which may not be trivial to design. 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."

Context: # 3.5 DYNAMIC PROGRAMMING

The LIS problem can be solved in output-sensitive O(n log k) (where k is the length of the LIS) instead of O(n²) by maintaining the LIS as it is updated and we can use a fancy binary search to find the appropriate insertion point to extend our single LIS. 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!

Context: # 6.2 BASIC STRING PROCESSING SKILLS
### Steven & Felix

1. (a) Do you know how to store a string in your favorite programming language?
   (b) How to read a given text input line by line?
   (c) How to concatenate (combine) two strings into a larger one?
   (d) How to check if a string starts with `.......` to stop reading input?

   I love CS2333 Competitive Programming. I also love Algorithm.

   > Note: You must stop after reading this line as it starts with 7 dots; after the first input block, there will be one looooooooccccccooooonng line...

2. Suppose we have our given string `T`. We want to check if another string `P` can be found in `T`. Report all the indices where `P` appears in `T` if `P` can be found in `T`. For example, if `T` is `I love CS2333 Competitive Programming. I also love Algorithm` and `P` is `love`, then the output will be the indices `{2, 49}`. If `P` is `book`, then the output is `{-1}`.

   (a) How to find the first occurrence of a substring in a string?  
   (b) Do we need to implement a string matching algorithm like Knuth-Morris-Pratt (KMP) algorithm discussed in Section 6.4, or can we just use brute-force?

3. Suppose we want to do some simplistic analysis of the characters in `T` and also transform each character into 1-byte binary code. The required analysis asks: How many digits, vowels, and consonants (lower/upper) representation alphabet so that we can send it over the T-CAN and back to (10) wherever it is the string of `T`?

4. Next, we want to make this one string into tokens (substrings) and store them into an array (which houses tokens). For this task, the delimiters of these tokens are spaces and punctuation (assuming standard ASCII words). For example:
   - `string = ['I', 'love', 'CS2333', '!', 'I', 'love', 'programming.']`
   
   (a) How to store an array of strings?

5. (a) Now, regarding the string that we want to analyze cryptographically and then find the frequency of each word safely. That is, we want to know tokens called: `['I', 'love', 'CS2333', '!', 'I', 'love', 'programming.']`.

6. (a) Which data structure best supports this word frequency counting problem?

7. (b) The given list has one more item that starts with `...` The length of this list item is not constrained. Count how many characters are there in the last item?

8. (c) How to read a string when we do not know its length in advance?

> *Note: This is not a term like the one used in our common dictionary.*

Context: # 3.6 Chapter Notes

Many problems in ICPC do not require one or combination (see Section 3.2) of these problem-solving paradigms. 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.

Context: Exercise 6.5.1.2 You want to save the predecessor information (the arrows) during the DP computation. 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
```

Context: # 1.2 TIPS TO BE COMPETITIVE

Additionally, we have a few other rules of thumb that are useful in programming contests:

- \( 2^{10} = 1,024 \) and \( 2^{20} = 1,048,576 \).
- Max 32-bit signed integer: \( -2^{31} = -2 \times 10^9 \) (for up to 9 decimal digits).
- Max 64-bit signed integer: \( \text{long} = 2^{63} \) (for up to 19 decimal digits). Use `unsigned` if slightly higher positive number is needed (e.g., \( 2^{64} - 1 \)).
- If you need to store integers \( \geq 2^n \), you need to use the Big Integer technique (Section 5.3).
- Program with nested loops of depth \( k \) running on \( n \) elements has \( O(n^k) \) complexity.
- If your program is recursive with recursive call per level and has \( L \) levels, the program has roughly \( O(n^L) \) complexity. But this is an upper bound. The actual complexity depends on what actions are done per level and whether some pruning are possible.

**Notes:**

- There are \( n! \) permutations and \( 2^n \) subsets (or combinations) of \( n \) elements.
- Dynamic Programming algorithms which find a 2D matrix in \( O(n) \) per cell is in \( O(n^2) \).
- More details in Section 3 later.
- The best time complexity of a comparison-based sorting algorithm is \( \Omega(n \log n) \).
- Most of the time, \( O(n^2) \) algorithms will be sufficient for most contest problems.
- The largest input size for typical programming contest problems must be \( < 10^6 \), because beyond that, the time needed to read the input (the I/O routine) will be the bottleneck.

   - (a) Load all webpages’ page rank to memory, sort (Section 2.1), and pick the top 10.
   - (b) Use priority queue data structure (heap) (Section 2.2).

2. Given a list \( L \) of up to \( 100 \) integers. You need to frequently ask the value of sum \( S, j \), i.e. the sum of \( L[j] + L[j+1] + ... + L[i] \). Which data structure should you use?
   - (a) Simple Array (Section 2.2.1).
   - (b) Simple Array that is pre-processed with Dynamic Programming (Section 2.2.1 & 2.3).
   - (c) Balanced Binary Search Tree (Section 2.2.2).
   - (d) Hash Table (Section 2.2.2).
   - (e) Segment Tree (Section 2.3.3).
   - (f) Funky Tree (Section 2.4.3).
   - (g) Fenwick Tree (Section 6.6).
   - (h) Suffix Array (Section 6.6.4).

3. Given a set \( S \) of \( N \) points randomly scattered on the 2D plane, \( N \leq 1000 \). Find two points \( P \) that has the greatest Euclidean distance. Is \( O(N^2) \) complete search algorithm that try all pairs possible?

2. You receive a TL response for your O(N) solution. However, maximum N is just 100. What should you do?
   - **(a)** Abandon this problem and go on. **(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 tricky 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 to choose both 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)** Consider that maybe your RTE runs on individual conditions. **(this lets you not know how to debug the WA code). There is not enough time and testing.**
   - **(b)** Send instead of trying to fix, and look for source code. 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).

Context: Additionally, we have a few other rules of thumb that are useful in programming contests:

- \( 2^{10} = 1,024 \) and \( 2^{20} \approx 1,048,576 \).
- Max 32-bit signed integer: \( -2^{31} = -1,073,741,824 \) (for up to 9 decimal digits).
- Max 64-bit signed integer: \( -2^{63} \) to \( 2^{63} - 1 \) (for up to 19 decimal digits). Use \texttt{unsigned} if slightly higher positive number is needed (i.e., \( 0 \) to \( 2^{64} - 1 \)).
- If you need to store integers \( \geq 2^{30} \), you need to use the Big Integer technique (Section 5.3).
- Program with nested loops of depth \( k \) running about \( n^k \) has \( O(n^k) \) complexity.
- If your program is recursive with recursive calls per level and has \( L \) levels, the program has roughly \( O(n^L) \) complexity. But this is an upper bound. The actual complexity depends on what actions come after level and whether some pruning are possible.
- There are \( n! \) permutations and \( 2^n \) subsets (or combinations) of \( n \) elements.
- Dynamic Programming algorithms which run in a 2D matrix in \( O(n^2) \) per cell runs in \( O(n^2) \) complexity. More details in Section 3 later.
- The best time complexity of a comparison-based sorting algorithm is \( \Omega(n \log n) \).
- Most of the time, \( O(n^2) \) algorithms will be sufficient for most contest problems.
- The largest input size for typical programming contest problems must be \( < 1M \); because beyond that, the time needed to read the input (I/O routine) will be the bottleneck.

## Exercise 1.2.2
Please answer the following questions below using your current knowledge about algorithms and their complexities. After you have finished reading this, you may be free to attempt this exercise again.

1. There are \( n \) webpages (\( n \leq 10^6 \)). Each webpage has a different page rank \( r \). You want to pick the top 10 pages with highest page ranks. Which method is more feasible?
   - (a) Load all webpages’ page rank to memory, etc. (Section 2.1), and pick the top 10.
   - (b) Use priority queue data structure (heap) (Section 2.2).

2. Given a list of \( L \) up to 100 integers. You need to frequently ask the value of sum \( S_j \), i.e., the sum of \( L[i] + L[i+1] + ... + L[j] \). What data structure should you use?
   - (a) Simple Array (Section 2.2.1).
   - (b) Simple Array that has pre-processed with Dynamic Programming (Section 2.2.1 & 3.5).
   - (c) Balanced Binary Search Tree (Section 2.2.2).
   - (d) Hash Table (Section 2.2.2).
   - (e) Segment Tree (Section 2.3.3).
   - (f) Fenwick Tree (Section 2.4.3).
   - (g) Dynamic Segment Tree (Section 6.6).
   - (h) Suffix Array (Section 6.6.4).

3. Given a set of \( S \) points randomly scattered on 2D plane, \( N \leq 1000 \). Find two points \( P \) that has the greatest Euclidean distance. Is \( O(N^2) \) complete search algorithm that truly all points possible?
   - (a) Yes, such complete search is possible.
   - (b) No, we must find another way.

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.)

Context: # 6.2 BASIC STRING PROCESSING SKILLS
## Steven & Felix

1. **Do you know how to store a string in your favorite programming language?**

2. **How to read a given text input line by line?**

3. **How to concatenate (combine) two strings into a larger one?**

4. **How to check if a line starts with '......' to stop reading input?**

I love CS2333 Competitive Programming. I also love Algorithm.

> **Note:** You must stop after reading this line as it starts with 7 dots. After the first input block, there will be one looooooooctooooning line...

2. **Suppose we have the string `T`. We want to check if another string `P` can be found in `T`. Report all the indices where `P` appears in `T` if `P` cannot be found in `T`. For example, if `T` is 'I love CS2333 Competitive Programming.' and `P` is 'I', then output should be:**
   - If `P` is considered default, then the character 'I' at index (2, 4) is output as part of the output. If `P` is 'love', then the output is [-1].

3. **How to find the first occurrence of a substring in a string?**
   - Do we need to implement a string matching algorithm (like Knuth-Morris-Pratt (KMP) algorithm discussed in Section 6.4), or can we just use library functions?

4. **Suppose we want to do some simple analysis of the characters in a string and also to transform each character into 10 binary digits. The required analysis step: How many digits, vowels, consonants, and consonants (lower/upper) appear in the lengths of the words can be found in `T`? Can you also find the lengths of the words?**

5. **Next, we want to break this string into tokens (substrings) and store them into an array of strings (look tokens). For this task, the boundaries of these tokens are spaces and punctuations (make break characters). For example, considering the variable `string`, if `T` contains the tokens `['I', 'love', 'CS2333', '!', 'I', 'love', 'algorithm']`.**
   - **How to store an array of strings?**

6. **Now, referring back, we must know the input. To do this, we need to count the frequency of each character statistically. That is, we want to know characters named 'I', 'a', 'l', 'o', 'c', 's', '3', '2', '5', '!', '', 'love', 'programming'. The frequency table is stored as:**
   - `['I', '1', 'love', '2', 'CS2333', '!', '5', 'algorithm']`.

7. **(a) Which data structure best supports this word frequency counting problem?**

8. **(b) The given list has one more item like the one asked in advance. The length of this list has been limited. Count how many characters are there in the last item?**

9. **(c) How to read a string when we do not know its length in advance?**

> **Note:** *This is not an error like the one used in our common dictionary.*

Context: # 1.2 TIPS TO BE COMPETITIVE

4. How to compute the "shortest path" between two vertices on a weighted Directed Acyclic Graph (DAG) with |V|, |E| < 100K. Which algorithm(s) can be used in contest settings?
   - (a) Dynamic Programming (Section 4.3.3, 4.4, 4.7).
   - (b) Breadth First Search (Section 4.2.2 & 4.2.4).
   - (c) Dijkstra's (Section 4.4.3).
   - (d) Bellman Ford's (Section 4.4.4).
   - (e) Floyd Warshall's (Section 4.5).

5. Which algorithm is faster (based on its time complexity) for producing a list of the first 10K prime numbers? (Section 1.5.1)
   - Size of Eratosthenes (Section 1.5.1).
   - For each number \( n \) (1 - 10K), test if isPrime(\( n \)) is true (Section 5.5.1).

6. You want to test if factorial of \( n \), i.e. \( n! \) is divisible by an integer \( m \). \( n \) is 10000. What should you do?
   - To find \( x! \mod m = 0 \) ... (Section 5.5.1).

7. You want to know all the occurrences of a substring \( P \) (of length \( m \)) in a (long) string \( T \) (of length \( n \)), if both \( m \) and \( n \) can go up to 10^ characters.
   - Use the following C++ code snippet:

```cpp
for (int i = 0; i < n; ++i) {
    bool found = false;
    for (j = 0; j < m && !found; j++) {
        if (P[j] != T[i + j]) found = false;
    }
    if (found) printf("%d is found in index %d in T\n", P, i);
}
```
   - The naive approach above will not work. We must use: (Section 6.4).

8. Same problem as in question 7 earlier, but now the number of points \( N \) is larger \( N \geq 1M \). Recall that points are randomly scattered on 2D plane.
   - The naive approach above will not work. We must use: (Section 7.3.7).

## 1.2.3 Tip 4: Master Programming Languages

There are several programming languages allowed in ICPC, including C/C++ and Java. 

While you should learn the basics of these languages, the programming language you should master is:

- Although we prefer C++, with built-in Standard Template Library (STL), using C can be used to master Java, while there have been popular libraries like BigInteger, String Processing, Graphics/Glared API, etc. 

Java is also a popular programming language due to its wide use in both ICPC competitions and its support for OOP and IDEs. 
The programming languages should be robust, such that from the latest ICC World Finals that there are programmers who coded in both C/C++ and Python. Do be aware that the "best" language to master is C++ as it is widely considered in these settings.

Context: # 1.3 GETTING STARTED: THE AD HOC PROBLEMS
© Steven & Felix

- **The Josephus-type problems**  
  The Josephus problem is a classic problem where there are people numbered from 1, 2, ..., n, standing in a circle. Every nth person is to be executed. Only the last remaining person will be saved. The problem is named after Josephus. 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**  
  These are classic problems:
  - Palindrome is a word (or actually a sequence) that can be read the same way in either direction. The common 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 of the original letters. The common strategy to check if two words are anagrams is to sort the letters of the words and compare the sorted letters. Example word: `tea`, world: `eat`. After sorting, both → `aet` would match → thus, they are anagrams.

- **Interesting Real Life Problems**  
  This is one of the most interesting categories of problems in UVA online judge. We believe that the real life problems are more interesting for those who are new to Computer Science. Given that not all new programmers solve real 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 said earlier, people usually get extra continuation when dealing with real life problems. Some of these problems will be much easier to solve than you think once you have mastered the Juan George/Candela class as it has lots of library functions to deal with time.

- **Just Ad Hoc**  
  Even after efforts to re-chart categorize the Ad Hoc problems, there are still many others that do not fit into a specific sub-category. The problem itself is the only description available. The solution for such problems is to simply follow/understand the problem description.

- **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.

Context: # 1.3 Getting Started: The Ad Hoc Problems

We will start this chapter by asking you to solve the first problem type in ICPCs and IOIs: the Ad Hoc Problems. According to [ICPC 2020](https://icpc.global), Ad Hoc problems are problems that cannot be classified anywhere else, where each problem description and its corresponding solution are "unique."

Ad Hoc problems appear more often in programming contests. Using a benchmark of total problems, the first problem selected to be the "ad hoc" problem is easy; it will be impossible to solve those problems without some reasoning or insight. But there exists a hierarchy of contest problems. In a training contest, your team is likely in the lower half (rank 30 to 40) or even in the bottom (rank 50 to 60), so the questions you can expect would only be easier. This may lead to 2–3 exceptions due to how they are structured, but for the usual problem set, you will have to work on the other 2 × 3 = 6 challenging tasks.

Here are three categories of problems we have listed mainly. The problems may vary in terms of their subcategories. Each category still contains a lot of problems, so we highlight into an extensive subset called "Easy" for beginners. There are three problems that we think are the most interesting for new time users for this category.

We believe that you can also make use of basic problems while allowing advanced data structures or algorithms that will be discussed in the later chapters. Many of these Ad Hoc problems are simpler but have the simple "tricky" notion. Now, try to solve problems from each category before reading the next chapter.

## The Categories

1. **(Super Easy)**  
   You should start these problems **AC** in under 7 minutes each!  
   If you are just starting competitive programming, we strongly recommend that you start your journey by solving simple problems from this category.

2. **(Game Card)**  
   There are many Ad Hoc problems involving game genres. The first game type is related to cards. Usually, you will need to parse the string input as standard cards (suits such as Diamonds (D), Clubs (C), Hearts (H), and Spades (S)) to derive the total number of quality pairs:  
   ```
   1 ≤ C, H ≤ 13, A ≤ 10; 
   ```

3. **(Game (Others))**  
   Another popular game that solves game aspects in programming contest problems are chess games. Some find it hard to find Ad Hoc (listed in this section). Once you're familiar, look at many ways to put 8-queens in an 8 × 8 board (listed in Chapter 3).  

***Note:*** Just remember to tell your players to do this. There are many possible problems to solve once you become familiar with those arrangements, A ≤ 4.

Context: # 1.2 TIPS TO BE COMPETITIVE
© Steven & Felix

Additionally, we have a few other rules of thumb that are useful in programming contests:

- \( 2^{10} = 1{,}024 \) and \( 2^{20} = 1{,}048{,}576 \approx 10^6 \).
- Max 32-bit signed integer: \( -2{,}147{,}483{,}648 \) = \( -2^{31} \) (for up to 9 decimal digits).
- Max 64-bit signed integer (long): \( 9{,}223{,}372{,}036{,}854{,}775{,}807 = 2^{63} - 1 \) (for up to 19 decimal digits).
- If you need to store integers \( > 2^{20} \), you need to use the Big Integer technique (Section 5.3).

1. Program with nested loops of depth \( k \) running in time \( O(n^k) \) complexity.
   - If your program is recursive with recursive calls per level and has \( O(n^k) \) complexity, beware! The program has lower complexity depending on what actions come next and whether some pruning is possible.

2. There are \( n! \) permutations and \( 2^n \) subsets (or combinations) of \( n \) elements.

3. Dynamic Programming algorithms which result in a 2D matrix in \( O(n) \) or less in \( O(k) \) complexity. 
   - More details in Section 3 later.

4. The best time complexity of a comparison-based sorting algorithm is \( \Omega(n \log n) \).

5. Most of the time, \( O(n^2) \) algorithms will be sufficient for most contest problems.

6. The largest input size for typical programming contest problems must be \( < 1 \text{ MB} \), because beyond that, the time needed to read the input (the I/O time) will be the bottleneck.

## Exercise 1.2.2
Please answer the following questions below using your current knowledge about algorithms and their complexities. After you finish reading this task or problem, you may be asked to return to this exercise again.

1. There are \( n \) webpages (with \( n < 10^6 \)). Each webpage has a different page rank \( r \). You want to pick the top 10 pages with highest page ranks. Which method is more feasible?
   - (a) Load all webpages' page rank to memory, sort (Section 2.1), and pick the top 10.
   - (b) Use priority queue data structure (Heaps) (Section 2.2).

2. Given \( N \) up to \( 10^6 \) integers. You need to frequently ask the value of sum of \( j, j+1, \ldots, i \) (the sum of \( L[j] + L[j+1] + \ldots + L[i] \)). What data structure should you use?
   - (a) Simple Array (Section 2.2.1).
   - (b) Simple Array that is pre-processed with Dynamic Programming (Section 2.2.1 & 2.3).
   - (c) Balanced Binary Search Tree (Section 2.2.2).
   - (d) Hash Table (Section 2.2.3).
   - (e) Segment Tree (Section 2.3.1).
   - (f) Fenwick Tree (Section 2.4.3).
   - (g) Sparse Table (Section 6.6).
   - (h) Suffix Array (Section 6.6.4).

3. Given a set of \( S \) points randomly scattered on \( 2D \) plane, \( N \) is 1000. Find two points \( S \) that has the greatest Euclidean distance. Is \( O(N^2) \) exhaustive search algorithm that try all pairs feasible?
   - (a) Yes, such complete search is possible.
   - (b) No, we must find another way.

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<bool>`.
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.

Context: # 3.2 COMPLETE SEARCH
**Steven & Felix**

Browse the literature of reference books[^41] to find more information on how to speed up your code. Practices like cache loading skill by discussing a harder problem in UVA online judge where the runtime of the best solution is on the order of \( O(N^3) \) is essential. Sharpen several variants of your accepted solution and check 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 Tip 1-6 above. If all else fails, abandon Complete Search.

## Remarks About Complete Search in Programming Contests

If a problem is declared to be solvable by Complete Search, it will often be done iteratively or using a recursive backtracking approach. Iterative approaches are used when one can derive the different constraints easily without recursion. Conversely, recursive approaches make it easier to explore and check all kinds of forms, enumerating all possible subsets of a small set. Recursive Backtracking allows the inference of the different states when some scenario occurs and needs the problem to be solved in stages; e.g., the states of the current configuration. Another thing to note is that the space of a problem that is solvable with Complete Search is large; the recursive backtracking that deals with the pruning of the search space is particularly useful.

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 Utilizing Complete Search:

1. **Iterative:**
   - UVA 100 - Ecological Bike Parking (try all possible combinations)
   - UVA 101 - The Simple Problem (finds map)
   - UVA 102 - Ecological Pyramids (bipartite map)
   - UVA 103 - Maximum Sum (brute-force that is not just enumeration)
   - UVA 104 - Regular Expression (try all combinations)
   - UVA 105 - Archery (greedy than combinations)
   - UVA 106 - 3D Chess (guess who will win)
   - UVA 107 - Sieve (gathered in one search)
   - UVA 108 - Traffic (find shortest path)

2. **Recursive:**
   - UVA 109 - Block Worlds (using simple blocks permutation)
   - UVA 110 - The Prince (look for chivalrous paths)
   - UVA 111 - Light and Camera (visualize projected angle)
   - UVA 112 - Blocked Path (to find the blocked paths)
   - UVA 113 - The Wedding (at least two of \( 3 \) pairs)
   - UVA 114 - Seven (Eureka).
   - UVA 115 - 3×3 Board (example of symmetry)
   - UVA 116 - Maximizing Pairing (optimal pairs)
   
3. **General:**
   - UVA 117 - The Lucky Number (need to yield the optimum)
   - UVA 118 - Painting (make sure minimal steps are used)
   - UVA 119 - 2D Game (use to derive max of visits)
   
4. **MISC:**
   - UVA 120 - Rectangle Equality (if find two they need to be equal)
   - UVA 121 - Random Number (to find a random number)
   
[^41]: Further reading suggestions are welcome, but note that it is merely an academic effort.
*"Get accustomed to maximum multiplication distance between \( 1 \) to \( N \). It should be okay, so we do not need BPS."*

Context: # 1.3 GETTING STARTED: THE AD HOC PROBLEMS
© Steven & Felix

- **The Josephus-type problems**  
  The Josephus problem is a classic problem where there are people numbered from 1, 2, ..., n, standing in a circle. Every kth person is to be executed. Only the last remaining person will be saved, or in other words, the one who is last stays. The smaller versions of this problem can be solved with plain brute force. The larger ones require better solutions.

- **Problems related to Palindrome or Anagram**  
  There are also classic problems:  
  Palindrome is a word (or rationally a sequence) that can be read the same way in either direction. The common 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 phrases) to get another word (or phrase) using all the original letters. The common strategy to check for anagrams is to sort the letters of the words and compare the sorted letters. Example word: `dog`, word: `god`. After sorting, both → `dgo` and `dgo` are equal, thus they are anagrams.

- **Interesting Real Life Problems**  
  This is one of the most interesting category of problems in UVA online judge. We believe that these real-life problems are interesting for those who are new to Computer Science. It feels like when programmers solve real problems it’s an extra motivational boost. 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. A sad affair, people usually get extra contradictory when dealing with real-life problems. Some of these problems will be math related. The solution for this problem is to simply follow Daniel’s advice in his book of library science to deal with time.

- **Just Ask**  
  Even after countless efforts to establish the Ad Hoc problems, there are still many others that require more knowledge on top of basic programming skills.

- **Ad Hoc problems from other chapters**  
  There are many more Ad Hoc problems which spread to other chapters, especially probabilistic 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.  

Types of problems with a number of programming problems, you will encounter some patterns.  
From C/C++ perspective, these patterns are:  
- Limitations to be included (limits, define, string, etc).  
- Data types to define (int, char, float)  
- For (i = 0; i < N; i++)  
- While (condition)  
- Recursion, etc.  
A competitive programming course (C/C++) can be listed as a basic example. For each Ad Hoc Problem, if he wants to solve another problem, he just need to open a new `*c*` file and import `include<competitive.h>`.

# 4.8 Chapter Notes

We ended this relatively long chapter by making a remark that this chapter has lots of algorithms and algorithms that are more in this book. 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. 

We believe that the graph materials in the 101 syllabus are already covered in this chapter.

Context: ## 5.2 AD HOC MATHEMATICS PROBLEMS

### Finding Patterns and Formulas
These problems require the problem solver to read the problem descriptions carefully to spot the patterns or functional relationships. Attacking them directly will usually result in little insight. The actual solutions are usually subtle and do not explicitly expose a rationale. 

Example: Let \( S = \{ 1, 4, 9, 16, 25, \ldots \} \). Given an integer \( N \), how many integers in \( S \) are less than \( N \)?

### Grid
These problems involve grid manipulation. The format of the grid can be complex, but the grid will always use some primitive rules. The traditional \( 2D \) grid can be a discrete lattice. 

The solution typically depends on the problem's constraints, simplifying the pattern to multiplicative/divisive grid or converting the given data into a simpler form.

### Number Systems or Sequences
Some Ad Hoc mathematics problems involve difficulties arising from existing (or fictional) Number Systems or Sequences and can trick to produce the number (sequence) when solving for the nth term. 

For example, verify if the given term (sequence) is valid according to definition. 

### Logarithms, Exponentiation, Power
These problems involve polynomial evaluation, exhaustion, de-rationalization, division, etc. We can potentially simplify or transform by solving the coefficients of the polynomial's lowest degree terms. 

Example:
- Exercise 5.2.1: What should be returned in \( C(x) + A_n \) to compute logarithm \( n \) (base \( b \))? 
- Exercise 5.2.2: What will be returned by \( \text{int}\log_{10}(1 + \log_{10}(a^3)) \)?
- Exercise 5.2.3: How to compute \( f'(x) \) with root of \( a \) in \( C(x) + C^{\prime}(x) \)?

### Polynomial
These problems involve polynomial evaluation, exhaustion, multiplication, division, etc. We can potentially simplify by sorting the coefficients of the polynomial's lowest degree terms.

### Base Number Variants
These are the mathematical problems involving base number, but they are not the standard conversion problem that can easily be solved with Java BigInteger techniques from Section 5.3.

### Just Ad Hoc
These are the other mathematical-related problems that cannot be classified as one of the above.

We suggest that problems—especially those who are new with mathematics-related problems—look to start further from programming or solving mathematics-related problems by trying at least 2 to 3 problems beforehand, specifically the ones that are highlighted as easy. Note: The problems listed constitute > 20% of the entire problems in this chapter.

Context: Exercise 4.4.2.1: For this variant, the solution is easy. Create a super source that is connected to all sources with edge weight 0. Then engineer the super source. Better still, simply ensure all edges become non-negative by adding the BPS log. As this is just the BPS, call it \( O(V + E) \).

Exercise 4.4.2.1: Our positive weighted graphs. For \( G \), graph with negative weighted edges, it runs forever until a correct result (mimic the original Dijkstra).

Exercise 4.4.3: Use `get-ucs`. This acts stores sorted pair of vertex information as shown in Section 4.4.3. Vertex with minimum distance is the first element in the (vertex, dist) tuple. To update the distance of a certain vertex from source, we search and then update the value pair. Then we return the new value pair.

Exercise 4.4.4: Solution is not shown.

Exercise 4.4.5.1: This behavior can be solved by adding a flag **[34]** or `adjFlag` **[36]** which will prevent if both `adjFlag` **[34]** and `adjFlag` **[36]** are near the MAXINT range, thus giving wrong answer.

Exercise 4.5.1: Each Warshall's works in graphs with negative cycles. For graph with positive cycles, refer to Section 4.5 about finding negative cycle.

Exercise 4.5.2: Running Floyd Warshall's directly on \( V \times 1000 \) will result in TLE. Use the property of SCC.

Exercise 4.5.3.2: Straightforward. Solution is not shown.

Exercise 4.5.4: Replace addition with multiplication. Check if the main diagonal > 1.0.

Exercise 4.6.1: Let \( B = 1. B = 119, C = -61 \).

Exercise 4.6.2: To find Adjacency List (for fast enumeration of neighbors) and Adjacency Matrix (for ease to edge weights/nodes capacity) of the same graph. Concentrate on copying those into **[34]** where \( 0 \leq v < MAX\_V \). We can also replace \( A[i][j] \) with \( I[j] \) to better `MAX-V` visited to speed the code a little for now.

Exercise 4.6.3: Solution is not shown.

Exercise 4.6.4: Solution is not shown.

Exercise 4.6.5.1: Solution is not shown.

Exercise 4.7.1: The better solution uses Least Common Ancestor (LCA).

Exercise 4.7.1: Solution is not shown.

# Chapter 5

Exercise 5.1: `ceiling` in C/C++ has `log` base (base e) and `log2` base (base 10). Java, lang.Math also has `log` (base 2) and `log10` (base 10), where `1 + log(log2)` has the rest that flags \( (x + e)^2 + \log(x) \).

Exercise 5.3.1.1: [Possible Exam]: Use intermediate computations modulo 10. Keep chopping away the trailing zeros because for every zero are added a multiplication from \( (0, 1) \). 

Exercise 5.3.1.2: If possible, treat as prime factors that are closer to \( (2 - 5) \). Use modulo arithmetic. 

Note: 25 is not divisible by either \( (7 \times 11) \). Alternative approach: Use modulo arithmetic.

Context: Exercise 6.5.12 You have to save the predecessor information (the arrows) during the DP computation. Then follow the arrows using recursive backtracking.

Exercise 6.5.13 The DP solution only need to restore the previous row as it will utilize the ‘space-saving trick’ [J. Albert et al.], but it’s much slower and less precise. The worst case may be O(n^2) (columns) due to the string with length as strong as 2n such that the chars have least columns (even memory). The time complexity of this solution will be O(m * n). The only drawback of this approach, as with any other space-saving trick is that we will not be able to reconstruct the solution. So if the actual solution is needed, we cannot use this space saving trick.

Exercise 6.5.14 Simplifying concentrate along the main diagonal with width d. We can speed up Needleman-Wunsch’s algorithm to O(n) by doing this.

Exercise 6.5.15 Solution is not shown. It involves Kadane's algorithm again (see maximum sum problem in Section 5.2.3).

Exercise 6.5.21 'spite'.

Exercise 6.5.22 Let m be the match = 0, mismatch = 1, insert and delete = negative infinity. However, this solution is not distinct, as we can simply use an O(mn) algorithm to scan both string 1 and string 2 and count how many characters are different.

Exercise 6.5.23 For details in LIS, (Longest increasing subsequence). The reduction to LIS is not shown. Draw it and see how to reduce this problem into LIS.

Exercise 6.6.1 Straightforward. Solution is not shown.

Exercise 6.6.2 'C' is found, CAT is not.

Exercise 6.6.3 'EVE'. Detail is not shown.

Exercise 6.6.4 'EVE'. Details not shown.

Exercise 6.6.5 The answer is the same as Exercise 6.6.3 which is 'EVE'.

Exercise 6.6.6 The answer is the same as Exercise 6.6.3 which is 'EVE'.

# Chapter 7

Exercise 7.2.1: 3.0

Exercise 7.2.1: (30, 40).

Exercise 7.2.2: The solution to 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 treat lines separately and then indicate the maximum value of the acceptable. Fortunately, this can be resolved by using the other linear equation y = α + βx = 0.

Exercise 7.2.2: 0 = x + 0 * y + 0 = 0.

Exercise 7.2.3: For 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 substituting the values of a point (either one) and the line gradient m. The code will look like this:

```cpp
struct line2 { double m, c; }; // another way to represent a line
```

In the next section, we will consider dynamic programming (DP) (Section 6.6). This includes to solve string processing problems where we have basic structures like Suffix Tree, Suffix Array must be used. We discuss these data structures and several specialized algorithms using these data structures in Section 6.6.

Context: 6.2 BASIC STRING PROCESSING SKILLS  
Steven & Felis

1. (a) Do you know how to store a string in your favorite programming language?  
   (b) How to read a given text input line by line?  
   (c) How to concatenate (combine) two strings into a larger one?  
   (d) How to check if a string starts with `'...'` to stop reading input?

I love CS2333 Competitive Programming. I also love Algorithms!

> Note: You must stop after reading this line as it starts with 7 dots. After the first input block, there will be one looooooocoocomooo line.

2. Suppose we have your string, `T`. You want to check if another string can be found in `T`. Report all the indices where `P` appears in `T` if `P` can be found in `T`. For example, if `T` is `I love CS2333 Competitive Programming` and `P` is `love`, then it should only show indices. Importantly, if we consider default, then the character `'l'` in index (1) is not part of the output. If `P` is `'love'`, then the output is `{2, 4}` if `P` is `'book'`, then the output is `{-}`.

   - How to find the first occurrence of a substring in a string?  
   - Do we need to implement a string matching algorithm (like Knuth-Morris-Pratt (KMP) algorithm discussed in Section 6.4), or can we just use brute force?

3. Suppose we want to do some sample analysis of the characters in `T` and also to transform each character into 1-byte numbers. The required analysis is: how many digits, vowels, and ASCII characters are in `T`? Could you describe (or lower) the lengths of these two spaces and arrays (like examples mentioned in this task)? 

   For string `T = 'I love CS2333', we'll have those tokens as `{'I', 'love', 'CS2333', 'competitive', 'programming', 'I', 'also', 'love', 'algorithm'}`. 
   
   - How to store an array of strings?

4. Next, we want to sort this array of strings lexicographically! 

   - Now, efficiently read any input to the array to do the same.  

5. (a) Which data structure best supports this word frequency counting problem?  
   (b) The given list has one more item that starts with `...`. The length of this list item is not constrained. Count how many characters are there in the last item?  
   (c) How to read a string when we do not know its length in advance?

> *Seriously, this is a text similar like the one used in our common dictionary.*

Context: # 5.10  Chapter Notes

Compared to the first edition of this book, this chapter has grown twice the size. 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 is the analysis of the visual content:

1. **Localization and Attribution:**

   - **Image 1**: The entire page is considered as a single image containing text content.

2. **Text Analysis:**

   - **Text Content**: The text is a section from a book or document titled "5.10 Chapter Notes" by Steven & Felix. It explains the breadth of mathematical topics covered in the chapter and provides additional pointers for topics not fully discussed.
   - **Significance**: This section serves as an expansion and a guide for readers interested in exploring more about combinatorics, number theory, and cryptography. It encourages further exploration beyond the chapter's content.

   - **Key Points**:
     - The chapter covers nearly twice as much material as previous editions.
     - Highlights unaddressed topics like Burnside’s lemma, Cayley’s formula, and others.
     - Mentions specific methods for integer factorization and primality testing, e.g., Pollard’s ρ algorithm and Miller-Rabin's algorithm.
     - References various mathematical conjectures and famous problems not fully elaborated.
     - Shows an example of programming exercises related to mathematics increased by 4.

4. **Tables:**

   - There is a simple enumeration of programming exercises and the number of pages in the chapter, showing an increase in both from previous editions.

10. **Contextual Significance:**

    - **Contribution**: The chapter notes provide a summary and reference to supplementary material, guiding the reader to think beyond the textbook. It sets a broader context for self-directed learning.

By capturing these elements, the visual presentation offers a valuable index of mathematical inquiries and learning pathways for students or enthusiasts, presenting a comprehensive wrap-up for the chapter.
