Hello, Codeforces!

I would like to invite everybody to participate in a mirror of Ural Regional School Programming Contest, which will be held on Timus Online Judge this Sunday, 31th of January, 12MSK.

For onsite participants this was a standard team contest with ICPC rules. Online participants may play it alone or in a team (up-to-3 people). Even though this is a school student competition with a certain number of simple problems, it also contains some very tricky problems, so it will be interesting for a wide range of people.

The problems were invented and prepared by Gmacem, teewar, BdE and me.

I also want to thank reshke for testing.

Good luck to everyone!
