I've tried submitting the lab 3 DequeCyclic.java to cssubmit and the automated
tester has been giving back errors. I'm not entirely sure how the system works but
judging from the analysis it gives it looks like it is just calling the code
in a way that gives an exception.
1.popLeft() <- without any pushLeft preceding it
Other submissions had similar problems.
Is it just the tester or do I need to fix my code do you think?
