Codeshark round #1 is going to take place on Codeshark this Friday morning at 2 PM (Tehran timezone). Codeshark website and the problem statements are in Persian, that's why I didn't put a link for time and date.
You can participate in the English version the next day (time) in Codeforces gym.
This contest will have 3 problems and each problem has some subtasks. Each subtask is a short answer algorithmic problem (like Projecteuler problems) and writers are AliA and me(PrinceOfPersia). Also, the duration is 4 hours.
I'd like to thank matrix (administrator of Codeshark) for his great helps.
Good luck and have fun.
UPD: There will be 12 subtasks (6, 3, 3).
UPD1: Schedule has changed (to 2 PM).
UPD2: Persian version is over.
Congratulations to the winners:
