162. Find Peak Element. Medium Array Binary Search. Leetcode Link. Problem Description. The problem presents an integer array called nums which is 0-indexed. We are tasked with finding an index of a peak element. A peak element is defined as an element that is strictly greater than its neighboring elements.
Problem. A peak element is an element that is strictly greater than its neighbors. Given a 0-indexed 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] = -∞.
Given a 0-indexed 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] = -∞. In other words, an element is always considered to be strictly greater than a neighbor that is outside the array.
