Codeforces Round #202 will take place today, September 27 at 19:30 MSK.
The idea behind the round was born when my friends and I were interning at Facebook this summer. This round probably has the highest number of authors for a Codeforces round to date. The authors of the problems are Azizkhan Almakhan azizkhan, Michael Kolupaev al13n, Filip Hlasek fhlasek, Ivan Mandura budabudimir and myself, Igor Demidov caustique.
I would also like to thank Gerald Agapov Gerald for his help in preparing the contest.
I hope you find problems interesting and diverse. I'm sure that everyone will find the problem to their liking.
Scores are as usual 500-1000-1500-2000-2500.
Good luck and have fun!
Congratulations to the winners!
Attention! Editorial for all problems is available!
