Virtual Contest
Rerun this round against its original field. TopCoder scoring, 75-minute coding phase, and the real competitors replayed as ghosts on the scoreboard.
A division runs one field at a time and starts on the quarter hour, so entering puts you in the next slot — at most fifteen minutes away — alongside everyone else who signs up before the gun.
