Christmas isn't a season. It's a feeling. — Edna Ferber

Hello everyone!

I would like to invite you to participate in another HackerEarth contest. This time it is Christmas Circuits. It's a long contest that will start on December, 16, 21:00 IST (check your timezone). Contest will run for 8 days.

The problemset consists of 7 traditional algorithmic tasks and 1 approximate problem. For traditional algorithmic tasks, you will receive points for every test case your solution passes — so you can get some points with partial solutions as well. For the approximation task, your score depends on the best solution in the contest so far. Check contest page for more details about in-contest schedule and rules.

The contest stories will be about Christmas. The main character in the stories will be Little Santa. I'd like to thanks KuchumovIlya for preparing these tasks, I_love_Tanya_Romanova for testing them and MikeMirzayanov for creating Polygon.

The contest will be RATED.

Happy Coding and Merry Christmas :)
