Web2 okt. 2024 · A heap is essentially used to get the highest priority element at any point in time. There are two types of heaps, based on the heap property — MinHeap and MaxHeap. MinHeap: The parent node is always less than the child nodes. MaxHeap: The parent node is always greater than or equal to the child nodes. Representation of MinHeap & MaxHeap Web23 jun. 2024 · 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. Representation of Max Heap: Max heap is represented as an array.
