WebThere is a simple, fast way to implement priority queues. A heap is a special kind of balanced binary tree. Sometimes it is called a binary heap to distinguish it from a memory heap. The tree satisfies two invariants: The priorities of the children of a node are at least as large as the priority of the parent. WebA heap is a tree-based data structure in which all the nodes of the tree are in a specific order. For example, if X is the parent node of Y, then the value of X follows a specific order with …

WebA binary min heap could hold our keys (or, more completely, our elements and their associated priorities, with the priorities being treated as keys). Our insertion algorithm would be how we'd implement enqueue, and our algorithm for removing the smallest key would give us an implementation of dequeueMin.
