Hello Codeforces community!

I am glad to announce that HackerRank 101 Hack 32nd edition will be held on 19th Dec 2015 at 18:00 UTC. You can sign up for the contest here. Though what's priceless is solving interesting problems and the thrill of competition, prizes make the competition fierce. Top 10 performers will get a HackerRank T-shirt.

Problems have been set by shangjingbo and tested by wanbo. The contest will consist of 5 problems with variable scoring distribution. We have tried our best to prepare a nice problem set. Hopefully everyone will enjoy. Also, you'll be able to enjoy the detailed editorials written by the setter.

Good luck and have fun!
