Hi Codeforces,
I am taking this opportunity to announce HackerRank HourRank 15, a 60 minute contest where the fastest coder wins!. The contest will be held on 16:30 UTC Saturday, 3rd December, 2016. You can sign up for the contest here. Contestants will be given 4 problems and 1 hour to solve. I recommend all of you to read all the problems as each problem contains some interesting subtasks. Top 10 global winners will get cool HackerRank T-shirts. Note that contest will be rated for all users.
As you can probably guess, i am author of this contest and i promise you all to deliver an interesting problem set with something for all. I really want to thank danilka.pro for testing all the problems and helping me to come up with nice problem set. My special thanks to Shafaet for bringing me back to problem setting and motivate me to work hard for this contest.
Scoring will be posted right before the contest and editorials will be published right after the contest.
Hope to see you participating.
Good Luck & Have Fun.
