Hi Codeforces !
I'd like to announce the fifth HackerRank HourRank round! The contest will be held on 16:30 UTC Monday, Feb 1 2016. 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.
HourRank 5 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.
