Max-Heap follows the property of a complete binary tree in which the value of the internal node is greater than or equal to the value of the children of that node. A node stored at k index in the array will have its left child held at index 2k + 1 and its right child at index 2k + 2. 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.
