In the very beginning of this post I would like to thank everyone who contributed to make this contest happen — both onsite and online versions. Thanks a lot to GlebsHP for helping to organize mirror on Codeforces.
Last year there were 4 teams that solved all the problems before contest ended so we tried to make this year's problems a bit harder. I would also like to mention that 2042 teams registered to this contest,676 managed to solve at least one problem and there is 1 teams that solved all the problems before contest ended. Congratulations to everybody!

I am sorry for it taking so long time: problems' authors live all over the world and it took several days rather than hours to assemble it. Editorial for geometry problem will be added as soon as I get it from the author, all others are here
