Program Plan Intro
Priority queue:
- Priority queue is another type of queue in which each item contains “priority” related with it.
- The element with high priority dequeued earlier than the element with low priority.
- If two or more elements have same priority then, they are processed according to their order.
- The two main operations done on priority queue is “add ()” and “removeMin ()”.
- The operation “add ()” is used to add an element to the queue.
- The process of removing an element from the priority queue using the method “removeMin ()” will always returns the minimum element.
