Code Problem
Find the first non-repeating character in a string.
AskAI
Given a string, this problem returns the index of the first non-repeating character in the string. If there is no such character, the problem returns -1.
Find the maximum average value in a given array of integers.
AskAI
Given an array of n integers, this algorithm finds the contiguous subarray of given length k that has the maximum average value. The output is the maximum average value.
Maximum Subarray Sum
AskAI
Given an array of integers, this algorithm finds the maximum sum of any contiguous subarray of the array. For example, given the input array [34, -50, 42, 14, -5, 86], the algorithm would output 137.
Sum of Odd Numbers in Array
AskAI
Given an array of integers, the function returns the sum of the odd numbers in the array.
Is One String a Permutation of the Other?
AskAI
This problem asks whether one string is a permutation of another. To check this, we can compare the two strings character by character. If they have the same characters in the same order, then one is a permutation of the other.
Odd Number Sum in Array
AskAI
The function should take an array of integers as input and return the sum of the odd numbers in the array.
