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 and feldsherov.
Scoring distribution will be quite unusual: 750-750-1000-2000-3000.
UPD System testing is over. Here are the top 10:
Congratulation! Also, problems seemed to be too tough, we should have probably made Div. 1 round. Anyway, thanks for participating, I hope you enjoyed it and learned something new!
