Circular queue avoids the wastage of space in a regular queue implementation using arrays. In this tutorial, you will understand circular queue data structure and it's implementations in Python, Java, C, and C++.
Algorithm for Enqueue OperationFollowing are the steps to perform the enqueue operation on a circular queue:1.Initialize an array or any data structure to store the elements of the circular queue. 2.Initialize two variables front and rear. 3.Check if the circular queue is full. 4.If it is...

Design your implementation of the circular queue. The 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"...

Useful for implementing several data structures (e.g. queues, Fibonacci heaps). An efficient queue can be built withoutusing two separate pointers forfrontand , and inserting just apointer to is sufficient for insertion or deletion since the predecessor is justthe next pointer in .reartailtail ...
