WebJun 12, 2024 · Then, the last element of the array is the peak element. However, if the array is sorted in descending order then the first element is the peak element. Naive Approach. The first solution that might come into your mind is that we can traverse through the array from the second element to the second last element. WebHow To Find The Peak Element In Python? Approach: In this approach, you have to compare the middle element of the array with its neighboring elements. You will find the peak element on the right side when the right-side neighbor is greater than the middle-element and on the left-side when the left-side neighbor is greater than the middle element.
