Find peak in array

WebThe peak element of an array can be found using the naive approach of linear search with time complexity O (N) or the optimized divide and conquer approach with time complexity O (logn). In this article, we will discuss both approaches in detail. The Linear Search Approach How it works & Implementation WebLocate the peaks of the signal. findpeaks reports only the rising edge of each flat peak.
