- Now given an NxN 2D array, find a peak in the array. This question can be easily solved in O(N^2) time by iterating over all the elements and returning a peak. However it can be optimized to be solved in O(NlogN) time by using a divide and conquer solution as explained here.
- A peak element is an element that is greater than its neighbors. Given an input array where 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. You may imagine that num[-1] = num[n] = -∞.

- Input : [8, 9, 10, 12, 15] Output: The peak element is 15 Input : [10, 8, 6, 5, 3, 2] Output: The peak element is 10 Naive solution would be to test all elements for peak by running a linear search on the array and return the element that is greater than its neighbors. Two special cases we need to handle.
