Binary search only work for sorted arrays

WebHere's the pseudocode for binary search, modified for searching in an array. The inputs are the array, which we call array; the number n of elements in array; and target, the number being searched for. The output is the index in array of target: Let min = 0 and max = n-1. WebJul 7, 2024 · Binary search is a search algorithm that finds the position of a target value within a sorted array. Binary search compares the target value to the middle element of the array.
