Let's call an array A a mountain if the following properties
hold:
A.length >= 3- There exists some
0 < i < A.length - 1 such that A[0] <
A[1] < ... A[i-1] < A[i] > A[i+1] > ... > A[A.length - 1]
Given an array that is definitely a mountain, return any i such that A[0]
< A[1] < ... A[i-1] < A[i] > A[i+1] > ... > A[A.length - 1].
