The data structure's priority queue is an extension of the "regular" queue. It's a generic data type that holds a collection of objects. It's similar to a "regular" queue, only the dequeuing parts are prioritized. The priority order removes the items with the highest priority from the queue first.

It's an abstract data type that allows you to keep track of your dataset. The “normal” queue follows the first-in-first-out arrangement. It dequeues elements in the same sequence as when the insertion operation was performed.
