Circular Queue

The efficient approach to avoid the wastage of the memory is to use the circular queue data structure. What is a Circular Queue? A circular queue is similar to a linear queue as it is also based on the FIFO (First In First Out) principle except that the last position is connected to the first position in a circular queue that forms a circle.
