Difference between a heap and a priority queue

A binary heap is a heap data structure that takes the form of a binary tree. Binary heaps are a common way of implementing priority queues. The binary heap was introduced by J. W. J.

"WebLet's assume that a binary heap is represented using a binary tree such that each node may have a left child node and a right child node. For this type of representation, we can still label the nodes of the tree in the same way as we label the nodes for an array representation. That is, the root node has a label 1. " - Binrary heap

The partially ordered tree illustrated previously is in fact a heap. Because a heap is a POT, the largest element is always at the root position. Because a heap is a complete binary tree, we can represent it using a vector. Putting these two observations together, we see that if we ...

In computer science, a heap is a specialized tree-based data structure which is essentially an almost complete tree that satisfies the heap property: in a max heap, for any given node C, if P is a parent node of C, then the key (the value) of P is greater than or equal to the key of C. In a min heap, the key of P is less than or equal to the key of C. The node at the "top" of the heap (with no paren…
