Good evening!
I thought it would be nice to have all problems from past Hacker Cups in one place to prepare for the upcoming contests. So I created training where you can solve 9 problems from 1-3 rounds of Facebook Hacker Cup 2012. Maybe it's the first and the last contest in your life where you can see time limit 100 seconds but don't worry — it happens because the problem has multitest (20 cases in one test) so in fact you have about 5 seconds for each case.
Wish you have a good time solving these tough problems. Good luck!
It looks like cool difficult ACM-ICPC contest: 9 problems/5 hours.
Well done ! ... I am worring about where could submit these problem just now.
Great, I hope that Google Code Jam will be available in Codeforces Gym.
It's quite hard work and it took me 4 hours to prepare this training. I did it because one can't test the solution on Facebook site and it's hard even to find these problems. But Code Jam has excellent site with tutorials and one has possibility to submit and check solutions immediately. I think, it's more comfortable to solve problems there.
