A peak element is an element that is greater than its neighbors. num[i] ≠ num[i+1], find a peak element and return its index. The array may contain multiple peaks, in that case return the index to any one of the peaks is fine. num[-1] = num[n] = -∞.[1, 2, 3, 1], ...

If such an index doesn’t exist, return -1.You can’t access the mountain array directly. You may only access the array using a MountainArray interface:MountainArray.get(k) returns the element of the array at index k (0-indexed). MountainArray.length() returns the length of the array....
