Hello Codeforces community,
I would like to invite you to join HackerRank's 101 Hack 50 on June 20, 2017.
There will be five tasks and three hours 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 kevinsogo, nabila_ahmed, zemen, Fedoriaka, and krismaz and tested by shashank21j, allllekssssa, bayleef, wanbo, and kevinsogo. I hope you'll enjoy the problems prepared by the community!
