WebMar 6, 2024 · Heap is a special tree-based data structure where the tree is always a complete binary tree. Heaps are of two types: Max heap and Min heap. In the case of the max-heap, the root node will have a higher value than its subtree, and for the min-heap, the root node will have a lower value than its subtree.
