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...

Circular Queue Data Structure - Learn about the Circular Queue Data Structure, its properties, operations, and applications in computer science.
It’s also known with alternative names such as a circular queue or ring buffer, but we will refer to it as a circular array throughout this article. The circular array has FIFO (First In, First Out) mechanism for element insertion and removal operations. Usually, the buffer will have a...
