An array element is a peak if it is NOT smaller than its neighbors. For corner elements, we need to consider only one neighbor. Example: Input: array[]= {5, 10, 20, 15} Output: 20 The element 20 has neighbours 10 and ...

Minimum removals required to convert given array to a Mountain Array
WebIn other words, peak can’t be the first or last element in the mountain array. int climb = 0 while (climb < n - 1 && X[climb] < X[climb + 1]) climb = climb + 1 if (climb == 0 climb == n - 1) return false If peak is present at some middle element, we run another loop from that position to check strictly decreasing order or elements. WebAn array A is a mountain array, if the following properties hold true: Length of an array is greater than equal to 3 (A.length >= 3). Only one peak element exist in the array. Peak element at index i follows (A [0] < A [1] < … A [i-1] < A [i] > A [i+1] > … > A [A.length – 1]) arrangement of elements. WebYou cannot access the mountain array directly. You may only access the array using a MountainArray interface: MountainArray.get (k) returns the element of the array at index k (0-indexed). MountainArray.length () returns the length of the array. Submissions making more than 100 calls to MountainArray.get will be judged Wrong Answer. schads award 22
