WebAug 3, 2024 · To heapify an element in a max heap we need to find the maximum of its children and swap it with the current element. We continue this process until the heap property is satisfied at each node. In order to heapify we move down from the root to the leaves. Hence this is also known as Down Heapify.

In computer science, a heap is a specialized tree-based data structure which is essentially an almost complete tree that satisfies the heap property: in a max heap, for any given node C, if P is a parent node of C, then the key (the value) of P is greater than or equal to the key of C. In a min heap, the key of P is less than or equal to the key of C. The node at the "top" of the heap (with no paren… WebApr 13, 2024 · Heap.
