Topcoder is a great platform organizing the algorithmic competitions that I have participated in and has had huge impact on my life. Meanwhile, Topcoder is also the place to see many coding talents.
Making Google cars driving themselves. See you on the road.
Video games (Dota2) and board games.
Enjoy the competition and have fun. Learn some useful new stuff for future competitions.
I hold the record for the most consecutive (9) TCO appearances (in any track, correct me if not). In algorithm competition, I corrected all 2^3=8 combination of system tests results. The hardest one is at TCO2009 semi-final, all submissions are wrong but no got challenged. 🙂
