Question: You are given a sorted array of n elements which has been circularly shifted. For example, 3 5 , 4 2 , 5 , 1

You are given a sorted array of n elements which has been circularly
shifted. For example, 35,42,5,12,23,26 is a sorted array that has been circularly
shifted by 2 positions. Give an O(log n) time algorithm to find the largest element
in a circularly shifted array. (The number of positions through which it has been
shifted is unknown to you.)
