Solve Five OA Coding Tasks

You are given five independent coding tasks. Implement all of the following functions. 1. **Add drama to text** - Input: a string `s`. - A **group** is a maximal contiguous sequence of non-whitespace characters. - Return a new string where every period `'.'` is replaced with an exclamation mark `'!'`, and one additional exclamation mark is appended after each group. - Preserve the original whitespace between groups. - Example: `"hi. there"` becomes `"hi!! there!"`. 2. **Filter and reverse even numbers** - Input: a list of integers `nums`. - Remove all odd numbers. - Return the remaining even numbers in reverse order relative to their original order. - Example: `[1, 2, 3, 4, 6, 5]` returns `[6, 4, 2]`. 3. **Compute a bounding rectangle** - Input: a non-empty list of coordinates, where each coordinate is a two-element list `[x, y]`. - Return a four-element list `[minX, minY, width, height]`, where: - `minX` is the minimum x-coordinate, - `minY` is the minimum y-coordinate, - `width = maxX - minX`, - `height = maxY - minY`. 4. **Find incorrect digit positions in a sum** - Input: three non-negative integers `num1`, `num2`, and `statedSum`. - Compute the correct value `num1 + num2`. - Compare `statedSum` against the correct sum digit by digit from right to left. - Return the zero-based digit indexes where the digits differ. The ones digit has index `0`, the tens digit has index `1`, and so on. - If the numbers have different lengths, treat missing higher-order digits as `0` while comparing until all digits of both numbers have been consumed. - Example: if `num1 = 99`, `num2 = 1`, and `statedSum = 190`, the correct sum is `100`, so the result is `[1]` because only the tens digit differs. 5. **Extract disallowed URLs for bot user agents** - Input: `lines`, a list of strings representing the contents of a text file, one line per string. - The file is similar to a robots file and contains sections. A new section begins when a line starts with the exact prefix `"User-agent:"`. - A section is relevant if its user-agent value, after trimming surrounding spaces, either: - is exactly `"*"`, or - ends with the exact suffix `"Bot"`. - Within every relevant section, collect the URL value after each line that starts with the exact prefix `"Disallow:"`. - Stop considering a section when the next `"User-agent:"` line begins or the file ends. - Return all collected URLs with duplicates removed. Matching is case-sensitive, so `"/A"` and `"/a"` are different URLs. Preserve the order of first occurrence.
