Hello Codeforces community!

I am glad to announce that HackerRank 101 Hack 45th edition will be held on 17th Jan 2017 at 16:30 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 me, and tested by wanbo and niyaznigmatul.

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!
