unofficial DWITE round 0

DWITE rounds, as typically, will begin this October. Though some students just can't wait that long. So A.J. and bbi5291 are putting together a mock round, as a warmup.

The planning and details are discussed in a CompSci.ca thread. The discussion really picks up around page 3, so maybe here is a more interesting place to start.

P.S.: this is an unofficial mock. It's not run on our servers. You don't earn points. I am not responsible if your password gets stolen. Though you will get yourself better prepared for the real deal. Besides, A.J. (who will be preparing the questions for this set) is pretty serious about his programming contests, so expect some challenge.
