Sorry, I misinterpreted the question as asking whether
the Deque ADT interface could be expanded.

Yes, you may declare helper functions within your Deque.c.
Such functions should be declared as static (so that they
cannot be accessed from another source file and thus are
not called directly by Qsort).

Thanks for pointing this out.
