I took my time on the first problem and I didn't have my environment set up correctly. I didn't realize until after the event was over that completion time was used to calculate the score. So I lost a lot of easy points as a result of my inexperience with TopCoder. I will be ready next time!
These SRMs are good practice for Google Code Jam (coming in May!). Hopefully I can post a respectable score at GCJ (maybe even secure a trip to the finals in Japan!)!
