Hello Codeforces Community!
I invite you to December Clash 2015. It will take place on Dec, 19-th at 9:30 MSK. Duration is 24 hours and submitting time doesn't matter so you can start whenever you want.
You will be given 5 algorithmic problems and one approximate (optimization) one. Some problems should be hard even for very strong competitors. All problems will have partial scoring (points for each test passed) and easier subtasks. Thus, everybody should find something for themselves.
EDIT — Problems are not necessarily sorted by the difficulty! Each problem is worth 100 points but scoring is partial so try to pass as many tests as possible! There is no penalty for incorrect submissions.
In my opinion problems are interesting and I hope you will have nice time solving them. It shouldn't be a typing competition for anybody. I'm very curious about the number of people with all 5 problems solved and about your scores in an approximate problem. We'll see.
I want to thank Akul Sareen (akulsareen) for his amazing help as a tester. He will also provide you editorials after a contest. And big thanks to HackerEarth admins — Arjit Srivastava (belowthebelt) and Ravi Ojha (raviojha2105).
Enjoy problems!
Oh, and there prizes. 5 T-shirts and 3 Amazon gift cards for the best participants. I guess it will make a fight for top spots a bit more interesting.
The contest is over! I hope you enjoyed it. Congratulations for top5, good job.

Is it a coincidence that top6 has nicely distributed scores? Roughly, the i-th place has score 510 - 10i.
