Priority Queue and Heap

• A Priority Queue is a data structure that consists of several queues each assigned a specific priority, and the data is stored and retrieved according to their priority assigned to them.

• In a heap, the records are stored in an array such that each key is guaranteed to be larger than the keys at two other specific positions.

• Heaps can be implemented using arrays or linked list.

• Common operations: Insert, delete any element, delete largest element, and change priority.
