Screencast of GCJ's Round 2. A much harder contest than Round 1, and I definitely struggled. Results below:
I submitted problems A, B, and C in 1:36:24, which would have been good for 61st, but I failed B's hidden test set and dropped to 312th. Ouch.
I knew a messy but workable way to solve D's easy set, although I mistakenly thought it would work on the hard too. I was coding right up to the end, but was probably at least 30 minutes away from getting any points.
