WebMar 12, 2024 · A peak element is one such that it is either greater than or equal to its neighbours. For the first and last element, it is enough to look at its only one neighbour. Examples: Example 1: Input: arr = {3, 5, 4, 1, 1} Output: Peak Element is 5 Explanation: 3 and 4 are lesser than 5, therefore 5 is a peak element (1 is also a peak element). WebFind peak elements in an array in time complexity of O(logN): Here, we will use a popular algorithm known as Divide and Conquer approach. In such an approach, we divide the array into two parts, solve them individually and conquer the shorter problem. Hence when the array is divided into two parts, the time complexity reduces logarithmically.
