Context: # EQUATION OF THE HYPERBOLA
## Exercise 50: Drawing Hyperbolas
Draw the following hyperbolas and find the eccentricity, foci, and vertices of each:
1. \( x^2 - 9y^2 - 16x + 18 = 0 \)
2. \( y^2 - 2x^2 - 12x = 34 \)
3. \( 4x^2 - 36y^2 + 18 = 0 \)
4. \( 6y^2 + 4x^2 - 16y + 1 = 0 \)
5. \( 3x^2 - 4y^2 - 8y + 1 = 0 \)
9. The general equation of the hyperbola having its axes parallel to the x-axis and y-axis involves four essential constants.
10. The equation of a hyperbola having its axes parallel to the x- and y-axes may be written in either of the following forms:
\[
\frac{xy}{a^2} - \frac{yx}{b^2} = 1
\]
or
\[
\frac{(x - h)^2}{a^2} - \frac{(y - k)^2}{b^2} = 1
\]
11. Find the equation of the hyperbola \( x^2 - y^2 = 16 \) when the origin is moved to the left-hand focus.
### Find the equation of the hyperbola satisfying the following conditions, and draw each figure:
12. The foci are \( (4, 0) \) and \( (10, 0) \), and one vertex is \( (6, 0) \).
- If the equation is assumed in the form given in 17a, \( a \) and \( b \) may be found from the fact that the distance from the center to a focus is \( \sqrt{a^2 + b^2} \).
13. The foci are \( (3, 5) \) and \( (3, -1) \), and the eccentricity is \( \sqrt{2} \).
14. The two vertices are \( (1, -6) \) and \( (-1, 8) \), and the eccentricity is \( \sqrt{2} \).
15. The two directrices are \( x = -2 \) and \( x = 4 \), and one focus is \( (5, 0) \).
16. The center is \( (4, 1) \), the eccentricity is \( \sqrt{13} \), and the point \( (8, 4) \) is on the curve.
17. The hyperbola passes through the four points \( (5, 1) \), \( (-3, -1) \), \( (-3, 1) \), and \( (-2, 1\sqrt{2}) \).
Image Analysis:
The image contains a page from a textbook focusing on hyperbolas. Here's the analysis:

Context: Figure 6.3 shows the commands applicable to cbrom. Displaying the options or help in cbrom is just like in DOS days; just type /? to see the options and their explanation. Now, get into a little over-the-edge cbrom usage. Remove and reinsert the system BIOS extension in Iwill VD133 BIOS. This BIOS is based on Award BIOS version 4.50PG code. Thus, its system BIOS extension is decompressed into segment 4100h during POST, not to segment 1000h as you saw in chapter 5, when you reverse engineered Award BIOS. Here is an example of how to release the system BIOS extension from this particular BIOS binary using cbrom in a windows console: E:\BIOS_M~1>CBROM207.EXE VD30728.BIN /other 4100:0 release CBROM V2.07 (C)Award Software 2000 All Rights Reserved. [Other] ROM is release E:\BIOS_M~1> Note that the system BIOS extension is listed as the "other" component. Now, see how you insert the system BIOS extension back to the BIOS binary: E:\BIOS_M~1>CBROM207.EXE VD30728.BIN /other 4100:0 awardext.rom CBROM V2.07 (C)Award Software 2000 All Rights Reserved. Adding awardext.rom .. 66.7% E:\BIOS_M~1> So far, I've been playing with cbrom. The rest is just more exercise to become accustomed with it. Proceed to the last tool, the chipset datasheet. Reading a datasheet is not a trivial task for a beginner to hardware hacking. The first thing to read is the table of contents. However, I will show you a systematic approach to reading the chipset datasheet efficiently: 1. Go to the table of contents and notice the location of the chipset block diagram. The block diagram is the first thing that you must comprehend to become accustomed to the chipset datasheet. And one more thing to remember: you have to be acquainted with the bus protocol, or at least know the configuration mechanism, that the chipset uses. 2. Look for the system address map for the particular chipset. This will lead you to system-specific resources and other important information regarding the address space and I/O space usage in the system. 3. Finally, look for the chipset register setting explanation. The chipset register setting will determine the overall performance of the motherboard when the BIOS has been executed. When a bug occurs in a motherboard, it's often the chipset register value initialization that causes the trouble. You may want to look for additional information. In that case, just proceed on your own. 5

Once you've invoked ctags like that, the tag file will be created in the current directory and named tags, as shown in shell snippet 9.8.

I condensed the shell output in shell snippet 9.8 to save space. Now, you can traverse the source code using vi. I'll start with flash_rom.c. This file is the main file of the flash_n_burn utility. Open it with vi and find the main function within the file. When you are trying to understand a source code, you have to start with the entry point function. In this case, it's main. Now, you can traverse the source code; to do so, place the cursor in the function call that you want to know and then press Ctrl+] to go to its definition. If you want to know the data structure definition for an object,5 place the cursor in the member variable of the object and press Ctrl+]; vi will take you to the data structure definition. To go back from the function or data structure definition to the calling function, press Ctrl+t. Note that these key presses apply only to vi; other text editors may use different keys. As an example, refer to listing 9.2. Note that I condensed the source code and added some comments to explain the steps to traverse the source code. Listing 9.2 Moving flash_n_burn Source Code // -- file: flash_rom.c -- int main (int argc, char * argv[]) { // Irrelevant code omitted (void) enable_flash_write(); // You will find the definition of this // function. Place the cursor in the // enable_flash_write function call, then // press Ctrl+]. // Irrelevant code omitted } 5 An object is a data structure instance. For example if a data structure is named my_type, then a variable of type my_type is an object, as in my_type a_variable; a_variable is an object.

## Exercise 1.2.4: Answers for situation judging are in brackets:
1. 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. Abandon the problem and go to another problem in attempt to solve two more problems or ask your team mates to debug the WA code, thus might help your team mates can find the bug for the WA code by looking at the printed code.

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. At this point, you have

# Software and Device Driver
This document discusses the locations of the registers in system-wide memory map.
## Registers
| Registers Type | Control Block | Device Physical Address | 4-GB System Memory Address |
|----------------|---------------|-------------------------|-----------------------------|
| BLR7 | RW | 7FFFF7000h | FFF90002h |
| BLR6 | RW | 6FFFF6000h | FFB9002h |
| BLR5 | RW | 5FFFF5000h | FB78002h |
| BLR4 | RW | 4FFFF4000h | FBFC002h |
| BLR3 | RW | 3FFFF3000h | FFB3002h |
| BLR2 | RW | 2FFFF2000h | FFB9002h |
| BLR1 | RW | 1FFFF1000h | FFB9002h |
| BLR0 | RW | 0FFFF0000h | FFB8002h |
**Table 11.1** BLR types and access memory map table for Winbond W39V040FA
The device physical address column in Table 11.1 refers to the physical address of the blocking registers with respect to the beginning of the chip in system-wide address space context. The meaning of each bit in the BLRs is shown in Table 11.2.
## Register Bits Function
| Bit | Function |
|------|--------------------------------------------------------------------------------------------|
| 7–3 | Reserved |
| 2 | Read Lock
1: Prohibit to read in the block where set.
0: Normal read operation in the block where clear. This is the default state. |
| 1 | Lock Down
1: Prohibit further to set or clear the read-lock or write-lock bits. This lock-down bit can only be set, not cleared. Only if the device is reset or repowered is the lock-down bit cleared.
0: Normal operation for read-lock or write-lock. This is the default state. |
| 0 | Write Lock
1: Prohibited to write in the block where set. This is the default state.
0: Normal programming or erase operation in the block where clear. |
**Table 11.2** BLR bits function table
*Tables 11.1 and 11.2 are identical to tables 9.1 and 9.2 in chapter 9. They are reproduced here for your convenience.*
*The size of a BLR is 1 byte.*

I used the call to the `DbgPrint` function in listing 9.33 when I was debugging the device driver. You can use the `DebugView` utility from Sysinternals to view the debug messages. `DebugView` is free of charge. To use it, run `DebugView` and activate the `Capture` > `Capture Kernel`, `Capture` > `Pass-Through`, and `Capture` > `Capture Events` options. Disable the `Capture` > `Capture Win32` option because it will clutter the output with unnecessary messages. The sample output for this driver is shown in figure 9.8.
You already know the changes in the `bios_probe` files that you learned in section 9.3 to accommodate the new PCI expansion ROM feature. There are the new files in source code version 0.31. Start with the new files in the driver.

```
## Stack values during j27 routine execution
Now, as you arrive in the `decomp_block_start` function, right before the `ret` instruction, the stack values shown in Figure 5.6 have already been popped, except the value in the bottom of the stack, i.e., `0x0A091`. Thus, when the `ret` instruction executes, the code will jump to offset `0x0A091`. This offset contains the code shown in Listing 5.31.
### Listing 5.31 Decompression Block Handler Routine
```
8000:0091 decomp_block_entry proc near
8000:0091 call init_decomp_engine ; On ret, ds = 0
8000:0094 call copy_decomp_result
8000:0097 call 0F000_0000
8000:009A ret
8000:009A decomp_block_entry endp
```

## 5.7 Modulo Arithmetic:
Some mathematical computations in programming problems can end up having very large positive (or very small negative) integral results that are beyond the range of largest built-in integer types, especially for the 64-bit Long Long C++ integer. In Section 5.5, we have seen that we can straightforwardly work with integers using prime factors. For such other problems, we are only interested in computing values modulo some integer \( m \).
For example, to compute \( a + b \) modulo \( m \), we must perform the addition as usual, but if the results exceed \( m \), we simply take the remainder when dividing by \( m \).
Here is a quick summary of some common modulo operations:
1. \( (a + b) \mod m = ((a \mod m) + (b \mod m)) \mod m \)
2. \( (a - b) \mod m = ((a \mod m) - (b \mod m) + m) \mod m \)
3. \( (a \times b) \mod m = ((a \mod m) \times (b \mod m)) \mod m \)
4. \( (a / b) \mod m \) is only valid if \( b \) has a modular inverse modulo \( m \) (which exists when \( a \) and \( b \) are coprime to \( m \)).
5. \( (a^b) \mod m \) can be computed efficiently using modular exponentiation.
## Programming Exercises related to Modulo Arithmetic:
1. UVa 10012 - *Software Check* (c mod a (m mod b) mod p)
2. UVa 10073 - *Big Mod* (c mod a (b mod m) mod p)
3. UVa 10374 - *Aside from Factor* (c mod b (m mod n) if using the trailing zeros)
4. UVa 10412 - *Couple Subtraction* - (a mod b gives the trailing zeros)
5. UVa 10712 - *Cousin Deep: Make Digit* - (a is the first number)
6. UVa 10149 - *Box of Chocolates* (keep arithmetic computations small modulo)
*“Multiples should be done in N.E.T., especially for 10 to discard the trailing zeros, then use % 1 Billion to only maintain the last few (maximum 10) zero digits.”*

# GEOMETRIC MAGNITUDES
## Exercise 7: Angles
1. The line through \( (–2, 3) \) and \( (12, –2) \) is parallel to the line through \( (10, 9) \) and \( (12, –2) \).
Hereafter the words "prove that" or "show that" will be omitted in the statements of problems where it is obvious that a proof is required.
2. The line through \( (–3, –5) \) and \( (–7, –2) \) is perpendicular to the line through \( (–2, 6) \) and \( (1, –4) \).
### Find the slope of the line which is perpendicular to the line through each of the following pairs of points:
3. \( (2, 1) \) and \( (5, –1) \)
4. \( (1, 3) \) and \( (4, 2) \)
5. \( (–2, 2) \) and \( (1, 0) \)
6. \( (–6, 0) \) and \( (6, –6) \)
7. If a circle is tangent to the line through \( (–2, 5) \) and \( (3, 8) \), find the slope of the radius to the point of contact.
8. Draw a circle with center \( (–3, –4) \) and passing through \( (5, 2) \). Then draw the tangent at \( (5, 2) \) and find its slope.
9. Find the slopes of the sides and also the altitudes of the triangle whose vertices are \( (3, 2) \), \( (4, 1) \), and \( (–1, –3) \).
10. Show by means of the slopes of the sides that \( (0, –1) \), \( (3, –4) \), \( (5, –2) \), and \( (–5, –2) \) are the vertices of a rectangle.
11. In Ex. 10, show that \( (1, 5) \), \( (4, 7) \), and \( (1, 4) \) are the vertices of a parallelogram having a diagonal parallel to the x-axis.
12. Draw the triangle whose vertices are \( A(2, 1) \), \( B(–1, –2) \), and \( C(–3, 3) \), and find the tangents of the interior angles of the triangle at \( A \).
13. If the slopes of \( l_1 \) and \( l_2 \) are 3 and –2 respectively, and the angle from \( l_1 \) to \( l_2 \) is \( \tan^{-1} 12 \).
The term "small" means the angle whose tangent is \( 1 \).
14. Find the slope of \( l_2 \) given that the angle from \( l_1 \) to the line through \( (1, 3) \) and \( (2, –2) \) is \( 45^\circ \); \( 120^\circ \).

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 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.

The ISR in the PIC_ISR_n_IRR_HouseKeeping procedure name refers to the in-service register, not interrupt service routine—especially, in the section that explains the POST jump table. The code in listing 12.12 shows that the first 32 entries of the 16-bit BIOS interrupt vectors are contained in a table—I will call it the interrupt vector table from this point. A rootkit developer is particularly interested in entry 13h and 19h because both of these entries are the vectors to interrupt 13h and 19h handlers.

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: # CONICS IN GENERAL
## 213. Illustrative Examples. Degenerate Cases.
By computing the value of the discriminant \( A \) (see \( \S 311 \)), we can always determine in advance whether or not a given conic is degenerate. But when \( A = 0 \), it is usually simpler to indicate the work of reduction for a given conic in the manner explained in Ex. 1, \( \S 212 \). In that case, if the equation happens to represent a degenerate conic, the fact will soon become apparent.
If the equation represents two lines, it follows from \(210\) that \( A = 0 \). It is evident that, conveniently, if \( A = 0 \), the step may be retraced, and the equation represents two lines.
1. Given the equation \( x - y - 6 = 3 - 2y + y^2 \), determine the nature of the conic and draw the figure.
Since \( A = -1 < 0 \), the conic is a hyperbola.
By rearranging the terms \( (x - 3)(y + 2) = 0 \), and when the origin is moved to \( O \), the new equation is \( x - 2y = 0 \).
A polynomial containing terms in \( x \) and \( y \), and no other terms, can always be factored. The factors may have real or imaginary coefficients.
The equation \( x - y = 0 \) may be written as:
\[
(y - 3)(y + 2) = 0,
\]
which represents two lines, \( y = 3 \) and \( y = -2 \). Since their equations have no constant terms, both lines pass through the origin \( O \), and the figure is easily drawn.
2. Given the equation \( -2xy + 3x + 4y - 12 = 0 \), determine the nature of the conic and draw the figure.
Here \( A = -2 \) and \( \Delta = 0 \), and hence the equation is degenerate. The factors of the polynomial are found simply as:
\[
(x - 3)(y - 6) = 0,
\]
hence, this represents the parallel lines \( x - y = 6 \) and \( y = x + 2 \), which are easily drawn.

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: # PROPERTIES OF THE ELLIPSE
## Exercise 44. Properties of the Ellipse
1. The axes of an ellipse are normal to the ellipse, and no other normal passes through the center.
In the above figure, \( F \) and \( F' \) are the foci of the ellipse; \( FT \) is the tangent at \( F(x,y) \), the slope of this tangent being \( m \); \( FY \) is the normal at \( F \); \( FE' \), \( OQ \), and \( FE \) are perpendicular to \( FY \); and \( RS \) and \( S'T' \) are perpendicular to the axes. Prove the following properties of the ellipse:
2. \( SN = \left(-\frac{e^2y}{f}\right) \).
3. \( S'N' = \left(\frac{y}{b}\right) \).
4. \( NS = \left(\frac{x^2}{a^2}\right) \).
5. \( NO = \left(-\frac{x}{a}\right) \).
6. \( OY = \left(-\frac{e^2x}{f}\right) \).
7. \( OT = \left(-\frac{y^2}{b^2}\right) \).
8. \( OQ = NY \).
9. \( OY \cdot NY = e^2 \).
10. \( OQ \cdot OY = e^2 \).
11. \( NT' \cdot NP' = FP' \cdot F'P \).
12. \( NT' \cdot NP' = FT' \cdot T'F \).
13. \( FE \cdot FE' = SF \cdot SA \).
14. As the tangent turns about the ellipse the locus of \( E \), the foot of the perpendicular from \( F \) to the tangent, is the circle having the center \( O \) and the radius \( r \).
A simple method is to represent the tangent \( PT \) by the equation \( y = \left(\frac{y_1 - y_0}{x_1 - x_0}\right)(x - x_0) + y_0 \), or perpendicular to \( FY \) with the equation \( y - y_0 = -\left(\frac{b}{a}\right)(x - x_0) \). Regarding these equations as simultaneous, eliminate \( s \) and obtain the equation of \( E \), which is the circle with center \( O \) and radius \( r \).

## 2.2 DATA STRUCTURES WITH BUILT-IN LIBRARIES

5. To clear/turn off the j-th item of the set, use `S &= ~(1 << j)`.
- `S = (10 base 10) = 1010 (base 2)`
- `j = 1 (2) => 1110 (base 2)` is the bitwise NOT operation
- `-------- AND`
- `S = (8 base 10) = 1000 (base 2)` // this new value 40 is updated to 5
6. To toggle the j-th item of the set, use `S ^= (1 << j)`.
- `S = (10 base 10) = 1010 (base 2)`
- `j = 2 (2) => 0010 (base 2) is shifted to left 4 times`
- `S = (4 base 10) = 0100 (base 2) // this new value 4 is updated to 5`
7. To get the first bit that is on (from right), use `A = (S & -S)`.
- `S = (8 base 10) = 1000 (base 2)`
- `A = (base 10) = 00000010 (32 bits, base 2)`
- `A = (base 10) = 00000000 (A and B from right to left)`
8. To turn off all bits in a set of size n, use `S = (1 << n) - 1`.
Example for n = 6:
- `S = 1 << 6 (base 10) = 100000 (base 2) is shifted to left 6 times`
- `--------`
- `S = 63 (base 10) = 111111 (base 2)`
Many bit manipulation operations are written as macros in our C/C++ example codes (but written as usual in our Java example codes as Java does not support macros).
Example code: `ch2.3_bit_manipulation.cpp`, `ch2.3_bit_manipulation.java`

## Exercise 62. Review
1. Find the equation of the loci of the foot of the perpendicular from the point \((-a, 0)\) upon the tangent to the parabola \(y^2 = 4ax\), and draw the locus.
This locus is called a **dropel**, which means "like a twisted band."
2. The locus of the foot of the perpendicular from the vertex of the parabola \(y^2 = 4ax\) upon the tangent is a **cubic**.
3. If \(r\) denotes the radius of a circle rolling on a straight line, the distance of any point on the radius from the center of the circle, and if the angle \(s\) is \(234^\circ\), show that the equations of the locus of the generating point on the radius are:
\[ x = r \sin \theta \]
\[ y = r - r \cos \theta \]
This locus is called a **cycloid**, which means "wheel-like."
4. Draw the curve in Ex. 3 when \(k < r\) and when \(b > r\).
When \(k < r\), the curve is called the **praxis cycloid**, and when \(b > r\), it is called the **curva cycloid**, which is described in §234.
5. Assuming that in the equation \(p = r \sin \theta\) is a positive constant, and taking the value \(v = \sqrt{2}r\) when \(2 > y\), show that it increases without limit when \(2\) decreases from \(0\) to \(r\) and that \(p \to \infty\) when \(2\) increases without limit. Draw the curve, and also consider the case of \(p = -\sqrt{2}r\).
This curve is called the **lituus**, which means "balancing staff." The reason for this name will be derived from the figure.
6. Draw the graph of the equation \(p = r \theta\).
This curve is called the **reciprocal spiral**.
7. Let \(P\) be any point on the reciprocal spiral \(p = r \theta\). Draw a direction clockwise from \(P\) and meeting the polar axis at the point \(Q\), and prove that the area \(r\) is constant.
If \(r, P, Q, P_1, P_2, \ldots\) are the vectors \(p_0, p_1, p_2\) ex are they represent the points of the logarithmic spiral \(r = e^k\), and if the vectorial angles \(\theta_0, \theta_1, \theta_2, \ldots\) are in arithmetic progression, then the radius vectors \(p_0, p_1, p_2\) are in geometric progression.

Context: # 1.2 TIPS TO BE COMPETITIVE
### © Steven & Felix
1. 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.

Context: 6.3 Ad Hoc String Processing Problems
===============================
Next, we continue our discussion with something light: the Ad Hoc string processing problems. They are programming contests problems involving strings that require more than basic programming skills and perhaps some basic string processing skills discussed in Section 6.2 earlier. We give a list of such Ad Hoc string processing problems with hints. These programming exercises have been further divided into subcategories.
### Cipher/Encode/Encrypt/Decode/Decrypt
* It is everyone's wish that their private digital communications are secure. That is, their messages (and only those) can be intended recipients. Many problems have been inspired for that purpose and many of these strings encode secrets, and it is indeed a problem. This is particularly true, of course, when we stress using **C**. It is interesting to learn a bit about **Computer Security/Cryptography** by solving these problems.
### Frequency Count
In this group of problems, the contestants are asked to count the frequency of a letter (say, base Direct Addressing Trick) or a word (handle, the solution is often using a balanced Binary Search Tree - the C++ STL map/Tree) - or hash table. Some of these problems are related actually to Cryptography (the previous sub-category).
### Input Parsing
This group of problems is best for I/O contestants as it enforces the input of I/O tasks to be formatted as simple as possible. However, there is no such restriction in IPC. Parsing problems range from simple forms that can be dealt with modified input reader, i.e., C/C++ - and that can range from basic problem involving simple grammars that requires recursive descent parser or Java Parsers (like Regular Expressions).
### Output Formatting
Another portion of problems that is also good for I/O contestants. This time, the output is the problematic part. In an I/O problem, an output is often not as ‘you might see’ for the contestants. Practice your coding skills by solving these problems as you will see.
### String Comparison
In this group of problems, the contestants are asked to compare strings with various criteria. This sub-category is similar to the string matching problems in the next section, but these problems may include more sophisticated functions.
### Ad Hoc
These are other Ad Hoc string related problems that cannot be (or have not been) classified as one of the other subcategories above.
### Programming Exercises related to Ad Hoc String Processing:
- **Cipher/Encode/Encrypt/Decode/Decrypt**
- UVA 0124 - Message Decode (interpret the message)
- **UVA 10243 - Trains (see the given algorithm)**
- **UVA 10714 - The best deal for mining gold**
- **UVA 10188 - The Garden (each character is mapped to either 2 or 3 digits)**
- **UVA 401 - The Decoder (data each character's ASCII value)**
- **UVA 508 - A Way to Muse (factor these numbers out)**
*Transcribed texts should apply even those which would not be clear with the text as an output or replicated in clarity.*

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: # Listing SMBIOS Information
Listings 10.1–10.3 show how to access the SMBIOS information present in the system for Windows-based machines. Nevertheless, this information is also provided by the WMI subsystem in Windows. It's possible that WMI doesn't parse all of the SMBIOS structure table in the system. In that case, you probably want greater control over the SMBIOS structure table by parsing it yourself and using the information for your purposes. The use of `bios_probe` version 0.34 to dump SMBIOS data in my system is shown in Figure 10.4.
## Figure 10.4 Dumping the SMBIOS Area in My System
The binary dump of the SMBIOS area is shown in hex dump 10.2.

*Steven & Felix*
## 5.5.1 Prime Numbers
A natural number starting from \(2\) (i.e., \(2, 3, 4, \ldots\)) is considered a prime if it is only divisible by \(1\) or itself. The first and the only even prime is \(2\). The next prime numbers are \(3, 5, 7, 11, 13, 17, 19, 23, \ldots\) and infinitely many more primes (proof in [31]). There are \(25\) primes in range \(0\) to \(100\), \(168\) primes in \(0\) to \(1000\), \(1229\) primes in \(0\) to \(10,000\), etc. Some large prime numbers are: \(2^{127}-1\), \(2^{521}-1\), \(2^{607}-1\).
Prime number theory is an important topic in number theory and the source for many programming algorithms. In this section, we will discuss algorithms involving prime numbers.
### Optimized Prime Testing Function
The first algorithm presented in this section is for testing whether a given natural number \(N\) is prime. Let us define \(i\) and \(p\). The most naive way is to test by divisibility, i.e., test if \(N\) is divisible by divisor \(i\) where \(i = 2, 3, \ldots, \sqrt{N}\). This of course works, but is not \(O(N)\) in terms of number of divisions. This is the best way to check if \(N\) is divisible by a non-\(1\) number when there is already evidence that \(N\) is not prime or has been divided by another. This needs to be augmented to test if \(N\) is divisible by other \(3, 5, \ldots, \sqrt{N}\), as we cannot simply skip multiples of \(2\).
The main loop goes through a series of checks, and the test is \(O(\sqrt{N})\), which is considerably better than \(O(N)\).
```python
def is_prime(N):
if N <= 1:
return False
if N <= 3:
return True
if N % 2 == 0 or N % 3 == 0:
return False
i = 5
while i * i <= N:
if N % i == 0 or N % (i + 2) == 0:
return False
i += 6
return True
```
### Sieve of Eratosthenes: Generating List of Prime Numbers
If we want to generate a list of prime numbers within a range \(0\) to \(N\), there is a better algorithm known as the Sieve of Eratosthenes, as described in "The Art of Computer Programming" by Donald Knuth. The steps are as follows:
1. First, it initializes an array to the range of numbers from \(2\) to \(N\) (inclusive).
2. Then, it marks each multiple of a number as a non-prime number. This takes \(O(N \log \log N)\) time.
As an example, consider the function for generating primes up to \(N\):
```python
def sieve_of_eratosthenes(n):
primes = []
is_prime = [True] * (n + 1)
for p in range(2, int(n**0.5) + 1):
if is_prime[p]:
for multiple in range(p * p, n + 1, p):
is_prime[multiple] = False
for p in range(2, n + 1):
if is_prime[p]:
primes.append(p)
return primes
```
This function will return a list of primes starting from \(2\) up to \(N\). It takes \(O(N \log \log N)\), which is quite efficient for generating lists of primes.
*Note: A small misunderstanding is to start from \(2\) instead of \(1\), but the difference is not that much.*

This arises due to the fact that a bubble can only be swapped for another if they are in the correct slots (like [1, 2, 3, 4, 5], swapping between them requires O(n) exchanges). For example, suppose the array is (0, 1, 0, 0, 1, 1). Contacting result is to be used to store Array implementations in Section 6.4.

## THE HYPERBOLA
Given the system of hyperbolas \( \frac{x^2}{a^2} - \frac{y^2}{b^2} = k \), where \( k \) takes various values but \( a \) and \( b \) are fixed, prove that:
1. Through each point of the plane there passes one and only one hyperbola of the system.
2. All the hyperbolas have the same asymptotes.
Letting \( E \) represent the equation \( y = \frac{k b}{a} \sqrt{1 + \frac{x^2}{a^2}} \), prove the statements in Ex. 28-31:
3. For each negative value of \( k \) numerically between \( -a \) and \( 0 \), \( E \) represents a hyperbola; for each other value of \( k \), \( E \) represents an ellipse.
4. All the curves \( E \) have the same focal points.
5. Given that \( a = 4 \) and \( b = 1 \), through (2, 1) two of the conics \( E \) are an ellipse and one a hyperbola, can be justified.
6. The two conics \( E \) in Ex. 30 intersect at right angles.
A simple proof is suggested by 153, 187, and 188.
7. Given a hyperbola, show how to find by construction the center and axes.
8. The locus of the center of a circle which is tangent to two fixed circles is a hyperbola the foci of which are the centers of the fixed circles.
9. Find the locus of the center of a circle which extracts from the axis chords of constant length \( 2a \) and \( 2b \).
10. Given that two vertices of a triangle are \( A(3, 0) \) and \( B(-3, 0) \), find the locus of the third vertex \( P \) if moves so that the angle \( \angle A B P \) is drawn, and know how to insert a triangle by means of its.
11. If two hyperbolas have the same vertices, and the perpendicular to the axis at any point of one hyperbola is at the other as \( E \), then \( MA \) and \( ME \) are to each other as the conjugate axes of the respective hyperbolas.

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.

# EQUATIONS OF ELLIPSES
24. The line joining one end of the minor axis of an ellipse to one of the foci is equal to half the major axis.
25. An ellipse in the form of half an ellipse is 40 ft wide and 15 ft high at the center. Find the height of the arch at intervals of 10 ft along its width.
26. An ellipse in which the major axis is equal to the minor axis is a circle.
27. In an ellipse with the fixed major axis \(2a\) and the variable minor axis \(2b\), as \(b\) approaches the directrix moves indefinitely away, the eccentricity approaches 0, and the focus approaches the center.
28. Draw an ellipse having the major axis \(2a\) and the minor axis \(2b\). Describe a circle having the major axis of the ellipse as diameter. Taking any point \(P\) on the ellipse and circle respectively, show that the coordinates \(MP\) and \(MP'\) are in the constant ratio \(a/b\).
29. Draw an ellipse, and then draw a circle on its major axis as diameter. Derive rectangles as shown in this figure. From Ex. 28 show that each rectangle \(R\) with a vertex on the ellipse and the corresponding rectangle \(R'\) with a vertex on the circle are related thus:
\[
R = m \cdot h.
\]
Then, increasing indefinitely the number of rectangles, show that the area of the ellipse is \( \pi a b \).
30. Prove the converse of the theorem of \(143\); that is, prove that the locus of a point which moves so that the sum of its distances from two fixed points \(F\) and \(F'\) is a constant \(2a\) is an ellipse of which the foci are \(F\) and \(F'\), and of which the major axis is \(2a\).

## Exercise 37: Properties of the Parabola
Draw the figure given on page 126, and prove that:
1. The tangent at \( P_1 \) bisects \( \angle P_1 A \) at right angles.
2. The lines \( TP', TP \), and the \( x \)-axis meet in a point.
3. The line joining \( A \) and \( L \) is perpendicular to \( TP' \).
4. The focus is equidistant from points \( T, P \), and \( M \).
5. The focus is equidistant from the points in which the tangent meets the directrix and the focal width.
6. The segment \( R'P \) is the mean proportional between the segment \( TP' \) and the focal width.
7. \( T'K = TF' \), where \( d \) is the distance from \( K \) to \( TP' \).
8. The proof of property 2, 130, is geometric. Give an analytic proof, using the lines of \( RP', TP' \).
9. Give an analytic proof of property 4, 130.
10. A line revolving about a fixed point on the axis of the parabola \( y = ax^2 \) traces the parabola in \( P \) and \( Q \). Show that the product of the ordinates of \( P \) and \( Q \) is constant, and likewise that the product of the abscissas is constant.
11. The line \( l \) revolves about the origin and the parabola \( y^2 = 4ax \) again in \( R \) and \( S \). Show that the ratio \( O'R : O'S \) is constant for all positions of \( l \).
12. Using property 1, 130, find a geometric construction for the tangent to a parabola at a point \( P \) on the curve.
13. Consider Ex. 12, using property 4, 130.
14. Find a geometric construction for the tangent to a parabola from a point not on the curve, using Ex. 1 above.
15. There are three normals from \( (h, k) \) to the parabola \( y = ax^2 \), and either one or three of them are real.

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.
- Ad Hoc problems involving basic geometry skills are listed in Section 7.2.

There are many other number theoretic problems that cannot be discussed one by one in this book. To close this chapter on number theory, let us tour through a few more programming problems related to number theory that are not classified under one of the categories above.
**Programming Exercises related to Other Number Theory Problems:**
1. UVa 10697 - DDP (a problem about "eventually constant" sequences)
2. UVa 1073 - Subtleties (Chinese Remainder Theorem)
3. UVa 10012 - Light, once light! (*check if it is in a square number*)
4. UVa 10922 - 2 the (test of divisibility by 11)
5. UVa 10929 - 2 the (test of divisibility by 11)
6. UVa 11920 - Congruence, difficult (and more recursive, 4 possible outputs)
7. UVa 11314 - The Huge One (*read as string, the divisibility theory of L(1...12)*)
8. UVa 11371 - Number Theory for Newbies (*the solving strategy is already given*)
5.6 Probability Theory
----------------------
Probability Theory is a branch of mathematics dealing with the analysis of random phenomena. Although there will be an inflection point to this realm, if it requires many times the inclusion of random events with certain statistical patterns, which can be studied and predicted, in programming contexts, problems involving probability are also worthwhile.
**Classification of the basic problems, one has to consider the guided formalism. Examples:**
- UVa 1060 - What is the Probability?
- UVa 1081 - Cards and Cats, etc.
**Exploration of the search space to count number of events (usually harder to count; may need combinatorial principles, Complete Search, or Dynamic Programming):**
- UVa 12043 - Has to be scaled with brute-force by trying all permutations and are hardly impossible to count for the similar instead A_n = (n - 1)! * (2^(n-1)). However, a more systematically observable can be handled using DP (and its overlapping subproblems) to count the number of events (n class assumed to be 2 ∗ even 6*).
**Programming Exercises about Probability Theory:**
1. UVa 1074 - Bicoloring (actually this is just a 2 color pick per corridor)
2. UVa 1079 - Generation (the probabilities)
3. UVa 1080 - Twinkling of the Sun (similar to UVa 1079, Jason Blagden)
4. UVa 1093 - Coin Drop (DP, 1 data type - just too easy!)
5. UVa 11131 - Dice Throwing (DP; scale (doubled, score for 6 sides, gold))
6. UVa 1151 - Eleven (including binaries, counting combinations)
7. UVa 1159 - Author (pick 1 author out of k, related to simplify)
8. UVa 12944 - 16 is 12 (the same line, 5 in this case)
> *Either pick a core first, then switch to a car; or pick a car first, and then switch to another car.*

"""QUERY: give a list of documents you have"""
Consider the chat history for relevant information. If query is already asked in the history double check the correctness of your answer and maybe correct your previous mistake. Use as much tokens as needed but at the same time be as efficient as possible. If you find information separated by a | in the context, it is a table formatted in Markdown - the whole context is formatted as md structure.
Important: Take a look at the QUERY and only the QUERY. Please try always to answer the query question. If the client ask for a formatting structure follow his advise.But if the question is vague or unclear ask a follow-up question based on the context.
