So, if the input is like nums = [8, 6, 4, 2, 0, 3], then the output will be True because, all elements are larger than their children. To solve this, we will follow these steps − n := size of nums for i in range 0 to n - 1, do m := i * 2 num := nums [i] if m + 1 < n, then

WebA heap is a binary tree inside an array, so it does not use parent/child pointers. A heap is sorted based on the "heap property" that determines the order of the nodes in the tree. Common uses for heap: To build priority queues. To support heap sorts. To compute the minimum (or maximum) element of a collection quickly.
