All problems are prepared by me. It will be my first HackerRank round so far. Also you may want to check my Codeforces round which held very lately Codeforces Round #352 (Div. 1) or Codeforces Round #352 (Div. 2).
There will be five tasks and two hours for you to solve them. Contest will be rated and top-10 contestants on the leaderboard will receive amazing HackerRank T-shirts!
I hope you will like the problemset. I tried my best to prepare interesting problems, so I strongly recommend you all to participate. Please read all of the problem statements during contest, because some problems may have subtasks and you don't need to find best solution to get points. Also some of the problems may be little harder than usual.
Editorials will be published right after the contest.
Scoring will be 20-40-70-80-100
UPD: Contest has ended! Congratulations to winners! Editorials for every problem are available now.
