Hello Codeforces community,
There will be five tasks and three hours for you to solve them. The contest will be rated and the top ten contestants will receive HackerRank T-shirts!
The problems are prepared by Yury Shilyaev (hloya_ygrt) and Vlad Vishnevsky (Vladik). (HackerRank only displays one author per problem, but the whole set was actually prepared by both.) I tested the problems and I found them to be interesting. I hope you'll enjoy the problems as much as I did!
