List of all Problem Types
^^^^^^^^^^^^^^^^^^^^^^^^^
The following is a list of all of the problem types that a Coding Contract can contain.
The list contains the name of (i.e. the value returned by
:js:func:`getContractType`) and a brief summary of the problem it poses.
+------------------------------------+------------------------------------------------------------------------------------------+
| Name | Problem Summary |
+====================================+==========================================================================================+
| Find Largest Prime Factor | | Given a number, find its largest prime factor. A prime factor |
| | | is a factor that is a prime number. |
+------------------------------------+------------------------------------------------------------------------------------------+
| Subarray with Maximum Sum | | Given an array of integers, find the contiguous subarray (containing |
| | | at least one number) which has the largest sum and return that sum. |
+------------------------------------+------------------------------------------------------------------------------------------+
| Total Ways to Sum | | Given a number, how many different ways can that number be written as |
| | | a sum of at least two positive integers? |
+------------------------------------+------------------------------------------------------------------------------------------+
| Spiralize Matrix | | Given an array of array of numbers representing a 2D matrix, return the |
| | | elements of that matrix in clockwise spiral order. |
| | | |
| | | Example: The spiral order of |
| | | |
| | | [1, 2, 3, 4] |
| | | [5, 6, 7, 8] |
| | | [9, 10, 11, 12] |
| | | |
| | | is [1, 2, 3, 4, 8, 12, 11, 10, 9, 5, 6, 7] |
+------------------------------------+------------------------------------------------------------------------------------------+
| Array Jumping Game | | You are given an array of integers where each element represents the |
| | | maximum possible jump distance from that position. For example, if you |
| | | are at position i and your maximum jump length is n, then you can jump |
| | | to any position from i to i+n. |
| | | |
| | | Assuming you are initially positioned at the start of the array, determine |
| | | whether you are able to reach the last index of the array EXACTLY. |
+------------------------------------+------------------------------------------------------------------------------------------+
| Merge Overlapping Intervals | | Given an array of intervals, merge all overlapping intervals. An interval |
| | | is an array with two numbers, where the first number is always less than |
| | | the second (e.g. [1, 5]). |
| | | |
| | | The intervals must be returned in ASCENDING order. |
| | | |
| | | Example: |
| | | [[1, 3], [8, 10], [2, 6], [10, 16]] |
| | | merges into [[1, 6], [8, 16]] |
+------------------------------------+------------------------------------------------------------------------------------------+
| Generate IP Addresses | | Given a string containing only digits, return an array with all possible |
| | | valid IP address combinations that can be created from the string. |
| | | |
| | | An octet in the IP address cannot begin with '0' unless the number itself |
| | | is actually 0. For example, "192.168.010.1" is NOT a valid IP. |
| | | |
| | | Examples: |
| | | 25525511135 -> [255.255.11.135, 255.255.111.35] |
| | | 1938718066 -> [193.87.180.66] |
+------------------------------------+------------------------------------------------------------------------------------------+
| Algorithmic Stock Trader I | | You are given an array of numbers representing stock prices, where the |
| | | i-th element represents the stock price on day i. |
| | | |
| | | Determine the maximum possible profit you can earn using at most one |
| | | transaction (i.e. you can buy an sell the stock once). If no profit |
| | | can be made, then the answer should be 0. Note that you must buy the stock |
| | | before you can sell it. |
+------------------------------------+------------------------------------------------------------------------------------------+
| Algorithmic Stock Trader II | | You are given an array of numbers representing stock prices, where the |
| | | i-th element represents the stock price on day i. |
| | | |
| | | Determine the maximum possible profit you can earn using as many transactions |
| | | as you'd like. A transaction is defined as buying and then selling one |
| | | share of the stock. Note that you cannot engage in multiple transactions at |
| | | once. In other words, you must sell the stock before you buy it again. If no |
| | | profit can be made, then the answer should be 0. |
+------------------------------------+------------------------------------------------------------------------------------------+
| Algorithmic Stock Trader III | | You are given an array of numbers representing stock prices, where the |
| | | i-th element represents the stock price on day i. |
| | | |
| | | Determine the maximum possible profit you can earn using at most two |
| | | transactions. A transaction is defined as buying and then selling one share |
| | | of the stock. Note that you cannot engage in multiple transactions at once. |
| | | In other words, you must sell the stock before you buy it again. If no profit |
| | | can be made, then the answer should be 0. |
+------------------------------------+------------------------------------------------------------------------------------------+
| Algorithmic Stock Trader IV | | You are given an array with two elements. The first element is an integer k. |
| | | The second element is an array of numbers representing stock prices, where the |
| | | i-th element represents the stock price on day i. |
| | | |
| | | Determine the maximum possible profit you can earn using at most k transactions. |
| | | A transaction is defined as buying and then selling one share of the stock. |
| | | Note that you cannot engage in multiple transactions at once. In other words, |
| | | you must sell the stock before you can buy it. If no profit can be made, then |
| | | the answer should be 0. |
+------------------------------------+------------------------------------------------------------------------------------------+
| Minimum Path Sum in a Triangle | | You are given a 2D array of numbers (array of array of numbers) that represents a |
| | | triangle (the first array has one element, and each array has one more element than |
| | | the one before it, forming a triangle). Find the minimum path sum from the top to the |
| | | bottom of the triangle. In each step of the path, you may only move to adjacent |
| | | numbers in the row below. |
+------------------------------------+------------------------------------------------------------------------------------------+
| Unique Paths in a Grid I | | You are given an array with two numbers: [m, n]. These numbers represent a |
| | | m x n grid. Assume you are initially positioned in the top-left corner of that |
| | | grid and that you are trying to reach the bottom-right corner. On each step, |
| | | you may only move down or to the right. |
| | | |
| | |
| | | Determine how many unique paths there are from start to finish. |
+------------------------------------+------------------------------------------------------------------------------------------+
| Unique Paths in a Grid II | | You are given a 2D array of numbers (array of array of numbers) representing |
| | | a grid. The 2D array contains 1's and 0's, where 1 represents an obstacle and |
| | |
| | | 0 represents a free space. |
| | | |
| | | Assume you are initially positioned in top-left corner of that grid and that you |
| | | are trying to reach the bottom-right corner. In each step, you may only move down |
| | | or to the right. Furthermore, you cannot move onto spaces which have obstacles. |
| | | |
| | | Determine how many unique paths there are from start to finish. |
+------------------------------------+------------------------------------------------------------------------------------------+
| Sanitize Parentheses in Expression | | Given a string with parentheses and letters, remove the minimum number of invalid |
| | | parentheses in order to validate the string. If there are multiple minimal ways |
| | | to validate the string, provide all of the possible results. |
| | | |
| | | The answer should be provided as an array of strings. If it is impossible to validate |
| | | the string, the result should be an array with only an empty string. |
| | | |
| | | Examples: |
| | | ()())() -> ["()()()", "(())()"] |
| | | (a)())() -> ["(a)()()", "(a())()"] |
| | | )( -> [""] |
