I'm glad to welcome all fans of programming!
The second qualifying round Yandex.Algorithm will take place today, and it was prepared for you by Artem Rakhov, Michael Mirzayanov and me.
Please pay attention that as well as during the previous qualifying round Codeforces's functionality will be a little cut down for the period of the competition. Don't worry, all will return into place after the round termination.
I remind the best 500 participants pass in Yandex. Algorithm 2011 Round 1 which will take place on May, 20th at 19.00
UPD: the contest is over, congratulations to the winner -
