Find a peak element gfg
WebGoogle Given an array of integers A, find and return the peak element in it. An array element is peak if it is NOT smaller than its neighbors. For corner elements, we need to consider only one neighbor. For example, for input array {5, 10, 20, 15}, 20 is the only peak element. Following corner cases give better idea about the problem. WebYou must solve it in O (log (arr.length)) time complexity. Example 1: Input: arr = [0,1,0] Output: 1 Example 2: Input: arr = [0,2,1,0] Output: 1 Example 3: Input: arr = [0,10,5,2] Output: 1 Constraints: 3 <= arr.length <= 10 5 0 <= arr [i] <= 10 6 arr is guaranteed to be a mountain array.
