Introduction to Priority Queue | Heaps | Data Structure | Logic and Code Explained

The priority queue is the queue data structure and the heap is the tree data structure that operates and organizes data. The priority queue is based on a queue data structure working as a queue with a priority function. The heap is a tree data structure used for sorting data in a specific order using an algorithm. Why heap is called a priority queue? Image result for the difference between heap and priority queue The heap is one maximally efficient implementation of an abstract data type called a priority queue, and in fact, priority queues are often referred to as "heaps", regardless of how they may be implemented. In a heap, the highest (or lowest) priority element is always stored at the root.
