Given a string, find the first non-repeating character.
The function should take in an array of integers and return the sum of all the odd numbers in the array. In the example given, the output would be 9.
The problem asks for the largest sum of a contiguous subarray in an array of integers.
This problem asks you to group all the anagrams in an array together. Anagrams are strings made up of the same letters, but in a different order. For example, " abcd" and "dcba" are anagrams, but "abcd" and "efgh" are not.
This problem asks whether two strings are permutations of one another. A permutation is defined as a rearrangement of the elements of an ordered list. This means that, for the two strings to be permutations of one another, they must have the same characters in the same order. In the given example, string1 is a permutation of string2 because both strings have the characters 'a', 'b', and 'c' in the same order.
Given an array of distinct integers, the goal is to find the length of the longest subarray with consecutive integers. For example, given the array [5, 2, 7, 1, 3, 8, 4, 9], the longest subarray with consecutive integers is [2, 7, 1, 3, 8], so the output would be 5.
The largest sum of non-adjacent elements in an array can be found by using a function. The input is an array of integers and the output is the largest sum of non-adj acent elements in the array.
