Data structure Description

The queue is an abstract data type, in which the element is inserted into the tail, and delete from the head. It stores the items using First in first out principle (FIFO). The queue can be implemented using an array or linked list. The enqueues insert an item to the tail. The dequeue removes the item from the head.

When the queue is empty, the dequeue throws empty queue exception. When the queue is full, the enqueue throws queue full exception.
