Oh well. At least it's generally accepted that Problem Set 4 (my set) was the worst set of them all for actual programming skill- it was an "really really hard" with a "typing speed contest trivial", and I wasn't quite up to speed on typing.
Simplifies weekend plans, since I won't have a TopCoder round to compete in.
By the way, dplass, you came in 69th place and qualified in your problem set. Congrats!
