Codeforces Round 350

Revision en2, by MikeMirzayanov, 2016-05-05 01:32:17

On May, 5, 16:05 (UTC) Codeforces Round 350 is going to start! Yes, pay attention to the non-standard start time.

I took advantage of my official position and the round is expected to be a bit experimental with an expanded set of problems. Perhaps for experienced participants (sorry, Div 1) it could seem easy. This time, emphasis was placed on the main target audience of the round: so in the round will be a lot of very simple problems, but even the top of the second division will find something interesting. In addition, one of the problems will be offered in two versions — in a simplified version with small constraints and in a harder version with greater constraints. Thus, if you immediately realize solution for large constraints, you can write and submit the same code on the both version.

The problem writers are me and fcspartakm. We hope that you will enjoy the problems and the round will be fun and useful!

The expected scoring is:

  • A: 500
  • B: 750
  • C: 1000
  • D1: 1000
  • D2: 500 (i.e. the complete solution of D is 1500 points)
  • E: 2000
  • F: 2500

Good luck!
