Hello, Codeforces!

Codeforces Round #278 will be held at Nov/21/2014 20:00 MSK for both divisions. Note that the time is 30 minutes later than regular Codeforces time, and Moscow is currently UTC+3.

The problem setters are taorunz and me. This is our first Codeforces round!

We'd like to thank Maxim Akhmedov (Zlobober), who helped us prepare the problems very much; also to thank MikeMirzayanov for Codeforces and Polygon platforms.

This round is involved in MIPT Fall Programming Training Camp, and top-20 of contestants from the camp will be rewarded with Codeforces T-shirts. For other contestants it will be regular Codeforces round.

Hope you enjoy the round, and wish you high rating.

UPD: Score distribution:

Div. 2: 500 — 1500 — 1500 — 2500 — 2500

Div. 1: 500 — 1500 — 1500 — 2000 — 2500

It's not for everyone that the optimal strategy is solving tasks in order. Make sure you've read all problems before the contest ends.

UPD: Very sorry that the round will be moved 20 forward due to technical reasons.
