Is always passing in the address of the pointer to the Deque instead of the pointer to the Deque itself enough to ensure our program will still work with the MOVING_DEQUES mode and any other time the value of the Deque might change?

In addition, how do we check if arguments to addD remD etc are invalid, or if the Deque object is inconsistent?
