Suppose you are given an array A of n distinct integers with the following property: There exists a unique index p such that the values of A[1... p] are increasing and the values of A[p... n] are is decreasing. For instance, in the example below we have n = 10 and p = 4: A [2, 5, 12, 17, 15, 10, 9, 4, 3, 1] Design a O(log n) algorithm to find p given an array A with the above property. Show the correctness of your algorithm
