Find the peak element in an array leetcode
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). WebApr 18, 2024 · A peak element is an element that is strictly greater than its neighbors. Given an integer array nums, find a peak element, and return its index. If the array contains multiple peaks, return the index to any of the peaks. You may imagine that nums[-1] = nums[n] = -∞. You must write an algorithm that runs in O(log n) time.
