Web14 de oct. de 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 −
