I'd like to announce 18th HourRank round! The contest will be held on 16:00 UTC Thursday, March 2 2017. Contestants will be given 4 problems and 1 hour to solve. You can sign up for the contest here. Top 10 winners will receive a HackerRank T-Shirt. HourRank 18 is prepared by me(svanidz1). I want to thank whole Hackerrank team, and especially Shafaet and Wild_Hamster for testing the tasks.
Wish you good luck.
