A. Imagine that your lab group (which may or may not be taking physics in an alternate reality) creates a string with screws at positions 1m, 2m, 3m, 4m, and 5m. You drop this string from a height of 5m, just as the lab instructions tell you to do, and you notice that the time intervals between screws hitting the cookie sheet get larger with each screw. The first two impacts are close together, then a little farther apart, then...

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.
