Hello Codeforces!
I'd like to announce the second HackerRank HourRank round! The contest will be held on 16:00UTC Monday, 2 November 2015 . Contestants will be given 4 problems and 1 hour to solve them. You can sign up for the contest here. Top 10 winners will receive a HackerRank T-Shirt. The contest is rated for all users.
Contest is prepared by me(svanidz1). I want to thank whole Hackerrank team, and especially Shafaet,wanbo and malcolm for testing the tasks.
Wish you good luck.
