Program Plan Intro
Queue:
The queue is a linear data structure used to store a set of data and is the collection of data that uses FIFO (first-in-first-out) order for performing operations.
- The queue is opened at its both ends. One end is for inserting items to the queue called a “rear” end and the other end is for removing the items from the queue called a “front” end.
- The two basic operations done on a queue data structure are,
- enqueue() – add an item to queue.
- dequeue() – remove an item from the queue.
- When the “enqueue()” method is invoked, it checks whether the queue is full or not. If the queue is full, it throws an exception.
- If the queue has slots available, then element is added at the rear end.
- When the “dequeue()” method is invoked on a queue, it checks whether the queue is empty or not. If queue is empty, it throws the exception.
- If the queue is not empty, then elements are deleted from the front end in first-in-first-out order.

A string represents a sequence of operations to be performed when implementing the Queue ADT. Theletter means the "put" operation, the asterisk means the "get" operation. What will remain in the queueafter performing the above operations?
