WebYou can do 2 binary searches: first to find the index i such that arr [i] > arr [i+1]. Apparently, (arr\ [1], arr [2], ..., arr [i]) and (arr [i+1], arr [i+2], ..., arr [n]) are both sorted arrays. Then if arr [1] <= x <= arr [i], you do binary search at the first array, else at the second. The complexity O (logN) EDIT: the code. Share WebApr 10, 2024 · Binary Search. Binary search is an algorithm used to find an element i.e., key in a sorted array. Binary algorithm works as below . Let us say that array is ‘arr’. Sort the array in ascending or descending order. Initialize low = 0 and high = n-1 (n = number of elements) and calculate middle as middle = low + (high-low)/2.
