Longest Common Prefix in an Array of Strings
AskAI
This problem asks you to find the longest common prefix among an array of strings. This can be done by comparing the first characters of each string, then the second characters of each string, and so on until a difference is found or the end of the shortest string is reached.
Permutation Check
AskAI
Given two strings, this function will check if one is a permutation of the other.
Two Sum
AskAI
The "Two Sum" problem is a code problem in the "Data Structures and Algorithms" category. Given an array of integers, the goal is to return the indices of the two numbers that add up to a specific target. For example, given nums = [2, 7, 11, 15] and target = 9, the solution would be to return [0, 1] because nums[0] + nums[1] = 2 + 7 = 9.
Length of longest substring without repeating characters
AskAI
This problem asks for the length of the longest substring without repeating characters. For example, given the string "abcabcbb", the answer would be 3, since the substring "abc " has a length of 3.
Sum of array elements
AskAI
This problem asks you to find the sum of all elements in an array.
Find the Maximum Sum of a Contiguous Subarray
AskAI
Given an array of n integers, the goal is to find the contiguous subarray whose sum is maximum.
Maximum Sum of Contiguous Subarray
AskAI
Given an array of n integers, the maximum sum of any contiguous subarray of the array is the sum of the largest subarray.
