The problems were set by pkacprzak and tested by me. The difficulty of this round will be not harder than CodeForces Div. 2 Round (maybe even easier). You'll be provided with 5 classic problems having partial scoring — you get points for every test that your solution passed, and also one approximate problem — your score for this task depends on how good your solution is comparing to current best solution (and don't be afraid of facing an approximate problem in a contest which lasts for 3 hours only ;) ). This contest will be a rated HE Round.
You'll be provided with statements in English, and there will also be a Russian version as well — thanks to shef_2318 for working on a problemset as a translator.
Also I want to thank to belowthebelt for helping with technical aspects of contest preparation.
In any case, Good Luck && Have Fun all of you! I hope to see you in standings :)
UPD. Please notice that problem statement of Bridges in Karak has been changed (there is an announcement about it in a contest as well — output format has been changed). We are sorry for it; in case you already attempted that problem — we strongly recommend you to check updated statement and try to fix your old solution. We'll do our best to minimize effect of this mistake in contest standings (exact decisions about rejudging old submissions and stuff like that will be made later), also contest has been extended by 15 minutes.
