Priority Queues

Priority Queues. Two kinds of priority queues: Min priority queue. Max priority queue. Min Priority Queue. Collection of elements. Each element has a priority or key. Supports following operations: isEmpty size add/put an element into the priority queue get element with min priority

Heaps, Heap Sort, and Priority Queues

Heaps, Heap Sort, and Priority Queues. Has a root at the topmost level Each node has zero, one or two children A node that has no child is called a leaf For a node x, we denote the left child , right child and the parent of x as left(x), right(x) and parent(x), respectively.
