Difference between Circular Queue and Priority Queue
Circular queue: Circular Queue is a linear data structure in which the operations are performed based on FIFO (First In First Out) principle and the last position is connected back to the first position to make a circle. It is also called ‘Ring Buffer’.
Priority queue: A priority queue is a special type of queue in which each element is associated with a priority and is served according to its priority.

||It can perform three operations like insert delete and display.
|Both the front and the rear pointers wrap around to the beginning of the array.
||It does not allow elements in sorted array.
|It overcomes the problem of linear queue.
||It allows duplicate elements.
|It requires less memory.
