Hello Codeforces community!

I am glad to announce that HackerRank 101 Hack 27th edition will be held on 23th July 2015 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 Devendra Agarwal 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.

If anyone are interested in sharing their knowledge, you can comment in this post or send message to me directly. We eagerly need bunch of good problems.

Good luck and have fun!
