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.

WebTo perform a binary search array must be sorted, it should either be in ascending or descending order. Step 1: First divide the list of elements in half. Step 2: In the second step we compare the target value with the middle element of the array. If it matches the middle element then search ends here and doesn’t proceed further.
