An element in sorted array can be found in O(logn) time via binary search. But suppose we rotate an ascending order sorted array at some pivot unknown to you beforehand. So for instance, 12345 might become 34512. Devise a way to find an element in the rotated array in O(logn) time. (explain how complexity came out to be logn)
