101 Hack 47 — HackerRank

Revision en7, by darkshadows, 2017-03-21 20:26:47

Hi everyone,

I'm excited to invite you to participate in 101 Hack 47. The contest starts at 1500 UTC, March 21. Note the unusual timing!

All problems have been prepared by me. You might have seen some problems and contests set by me on various platforms. This is my third round on HackerRank, after 101 Hack 26 and 101 Hack 40. Also, here is an old collection of my problems.

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'd like to thank kevinsogo for testing the problems and his contribution towards fixing problem statements and editorials. It's always a pleasant experience to work with him.

I have tried to create a balanced and interesting problem set. I suggest you read all problems, since there are subtasks and partial scoring. Problems are very much on the easier side compared to previous contests and I bet a lot of full scores(like a lot, seriously!).

Editorials(written by me) will be published right after the contest.

Update 1: Scoring will be 15 — 30 — 45 — 65 — 80. Update 2: Contest has ended. Congratulations to top 10 for getting full scores. Top 10 are:

  1. I_love_Tanya_Romanova
  2. dreamoon_love_AA
  3. arsijo
  4. KrK
  5. kraskevich
  6. uwi
  7. LHiC
  8. MadNick
  9. HellKitsune
  10. black_horse2014

Update 3: Editorials are up.
