Hi, Codeforces!

Educational Codeforces Round 3 will take place on 19 December 2015 at 18:00 MSK for the first and second divisions. You can read about educational rounds here and here. A lot of time have passed since the previous round. I hope that the next rounds will be more regular.

<This paragraph wasn't changed>

The round will be unrated for all users and it will be held with extented ACM ICPC rules. You will have two hours to solve six problems. After that you will have one day to hack any solution you want. You will have access to copy any solution and test it locally.

</This paragraph wasn't changed>

This time the round was prepared not only by me, Edvard Davtyan. Firstly, thanks a lot to Alexey Dergunov dalex who shared one of his problems with well-known idea. Also thanks a lot to Alexandr Frolov fcspartakm, Vitaliy Kudasov kuviman and Arthur Svechnikov ikar for their help in preparing problems. MikeMirzayanov helped us to invent the problems. Also thanks a lot to Maria Belova Delinur for translating the problems from my RussianEnglish to English :-)

I hope you will enjoy the problems.

Good luck and have fun!

UPD1: The first part of competition is over. I hope that you enjoyed the problems. Now you let's hack other solutions :-)

UPD2: The editorial is ready.
