Difference between dequeue and priority queue in data structure

Answer 1

A priority queue is a modified version of a queue or stack. Its principle of operation is very simple. An element of higher priority is output before an element of lower priority. In the case of two elements having the samepriority, they are output according to their order in the queue or stack.

Difference between dequeue and priority queue in a data structure  is given below:-

Explanation:

A queue is a list in which the addition is done at one end and the elimination is done at the other.

Dequeue:-

• Dequeue is a list where each end accepts inclusion and elimination.
• Dequeue is a queue where you can attach and delete items from both ends of the queue.
• It has two sides, the front, and the back, and the items remain in the set.

Priority queue:-  

• Elements can be added in any order, but the elimination of the items is in sorted order.
• A priority queue is a conceptual data form that is similar to a standard queue or a stack database model, but where moreover each component has a "priority" associated with it.
• Although priority queues are often set up like heaps, they are narratively distinct from heaps.
