Hello Codeforces Community, I am glad to share HackerRank World Codesprint 9 starting on 27th January 2017. The contest duration is 24 * 2 =48 hours.

The winners of the contest will win up to 2000USD cash prizes. Also, there are opportunities to win T-shirts and Amazon Gift cards.

The contest will be rated. If two person gets the same score, the person who reached the score first will be ranked higher.

There will be 7 normal algorithmic challenges and 1 approximate challenge in this contest. I highly recommend you to read all the problems. Most of the problems contain cool figures and subtasks!

The problems are prepared by zemen, Wild_Hamster, kevinsogo, allllekssssa, forthright48, nabila_ahmed and bishop15. Thanks to danilka.pro, niyaznigmatul and wanbo for helping to test the problems. And again special thanks to Wild_Hamster for helping to finalize everything.

(By the way, danilka.pro is now known as danilka.pro!)

Update: Contest is starting in less than 5 minutes.

Update: The contest ended. We will soon announce the winners. Meanwhile, let us know if you liked or didn't like the problem-set.

Happy Coding!
