Find an algorithm to determine if the array represents a min-d-heap.
WebGiven a binary tree, check if it is a min-heapor not. In order words, the binary tree must be a complete binary tree where each node has a higher value than its parent’s value. For example, the following binary tree is a min-heap: On the other hand, the following binary tree is not a min-heap: Practice this problem 1. Recursive Solution WebTo add an element to a min-max heap perform following operations: Append the required key to (the end of) the array representing the min-max heap.
