WebOct 14, 2024 · Heap is a special case of balanced binary tree data structure where the root-node key is compared with its children and arranged accordingly. If α has child node β then − key (α) ≥ key (β) As the value of parent is greater than that of child, this property generates Max Heap. Based on this criteria, a heap can be of two types − WebThe heap data structure, specifically the binary heap, was introduced as a data structure for the heapsort sorting algorithm. Heaps are also crucial in several efficient graph algorithms such as Dijkstra’s algorithm. In a heap, the highest (or lowest) priority element is always stored at the root.
WebJul 30, 2024 · A Binary Heap is a complete binary tree which is either Min Heap or Max Heap. In a Max Binary Heap, the key at root must be maximum among all keys present in Binary Heap. This property must be recursively true for all nodes in that Binary Tree. Min Binary Heap is similar to MinHeap.
