Tomorrow Codeforces Round #342 is going to take place. It will share the problemset with Moscow Olympiads in Informatics for students of grades from 6 to 9. Though, grades from 6 to 9 in Russia usually match the ages from 12 to 15, I guarantee that everyone (even Div. 1 participants) will find some interesting problems to solve. Problems were selected for you by the Moscow jury team: Zlobober, _meshanya_, romanandreev, Helena Andreeva and me; and prepared by members of our scientific committee: wilwell, sender, iskhakovt, thefacetakt и feldsherov.
Scoring distribution will be quite unusual: 750-750-1000-2000-3000.
