Hello Codeforces Community!

I invite you all to join HackerRank's HourRank 23 on September 9, 2017, at 20:30 IST.

There will be three tasks in the round and one hour for you to solve them. The contest will be rated and the top ten contestants will receive HackerRank T-shirts!

The problems are prepared by Wild_Hamster, zoomswk and me, and tested by shashank21j, Birjik and me. I hope you'll like them!

This round is a bit harder than the usual for HourRank. I suggest you read all the problems.

Good luck and Happy Coding!
