This problem asks you to return the sum of the elements in an array. For example, given the input [1, 2, 3], the output would be 6.
The problem is to find the first non-repeating character in a string. The input is a string and the output is the first non-repeating character in the string.
The "Two Sum" problem asks us to find the indices of two numbers in an array that add up to a specific target. We are given that each input has exactly one solution, and we cannot use the same element twice. An example is provided, where the array is [2, 7, 11, 15] and the target is 9. The solution in this case is [0 , 1], since 2 + 7 = 9.
This problem deals with determining whether an array contains duplicates. The function should return true if any element appears more than once in the array, and false if every element is distinct.
Given an array of n integers, this code problem finds the contiguous subarray of given length k that has the maximum average value. The output is the maximum average value.
Given an array of n integers, find the contiguous subarray of given length k that has the maximum average value. Output the maximum average value.
This function takes in an array of integers and returns the sum of all the elements in the array.
Find the maximum sum of a contiguous subarray of length k in an array of n integers.
