A priority queue is a type of queue in which each element has a priority associated with it

In priority queue  elements with a higher priority are dequeued before elements with a lower priority.

Priority queues can be implemented using a variety of data structures, such as arrays, linked lists, or heap

In a priority queue, the priority of an element is determined by its value or by a priority function that is applied to the element

Some common operations on a priority queue include enqueuing , dequeuing and peek

A priority queue can be used to store a variety of data types, such as integers, strings, or objects

In a multi-threaded environment, a priority queue can be used to prioritize tasks that need to be completed by a group of worker threads
