Hello Codeforces community!

I am glad to announce that HackerRank Weekly 24th edition will be held on 10th Oct 2016 at 07:00 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.

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.

Each day you get to solve a challenge whose difficulty level increases as the week progresses. Challenge score will decrease by 10% every 24 hours.

Good luck and have fun!
