WebA Binary (Max) Heap is a complete binary tree that maintains the Max Heap property. Binary Heap is one possible data structure to model an efficient Priority Queue (PQ) Abstract Data Type (ADT). In a PQ, each element has a "priority" and an element with higher priority is served before an element with lower priority (ties are either simply resolved arbitrarily or … WebWe can use the procedure heapify in a bottom-up manner to convert an array A[1;:::;n], where n = length(A), into a heap. Since the elements in the subarray A[bn=2c+1;:::;n] are all leaves of the tree, each is a 1-element heap to begin with. The procedure build-heap goes through the remaining nodes of the tree and runs heapify on each one.
