Queue: The queue is a linear data structure used to store a set of data. The queue is a collection of data that are accessed in FIFO (first-in-first-out) order for performing the operations. A queue is opened at both its ends. One end is for inserting items to the queue and the other end is for removing the items from the queue. The two basic operations performed on queue are, enqueue() – add an item to queue. dequeue() – remove an item from the queue. The queue does not have fixed size.
