A deque is a data structure consisting of a list of items, on which the following operations are possible:
• push(x): Insert item x on the front end of the deque.
• pop(): Remove the front item from the deque and return it.

• inject(x): Insert item x on the rear end of the deque.
• eject(): Remove the rear item from the deque and return it.
Write routines to support the deque that take O(1) time per operation.

A deque (pronounced deck) is an ordered set of items from which items may be deleted at either end and into which items may be inserted at either end. Call the two ends left and right. This is an access-restricted structure since no insertions or deletions can happen other than at the ends. Implement a deque as a doubly-linked circular list with a header. Write InsertRight and DeleteLeft.

Create a Deque class based on the following description of deque (double-ended queues). A dequeue is a double-ended queue. You can insert items at either end and delete them from either end. Therefore, the deque offers two insert operations and two remove operations: insertLeft() and insertRight() removeLeft() and removeRight(). Deques may also have "peek" methods ( peekLeft() and peekRight() )that let you see the left or right item in the deque without remove the item from the deque. For this...
