CF 1062763 - Два из трёх

I don’t have the actual statement of Codeforces 1062763 “Два из трёх” available from what you provided here, and the editorial depends heavily on the exact operations and constraints.

Solution

I don’t have the actual statement of Codeforces 1062763 “Два из трёх” available from what you provided here, and the editorial depends heavily on the exact operations and constraints.

Right now the “Problem Statement / Input / Output” sections are empty, so any full solution would be guesswork and very likely incorrect.

If you paste the statement (or even just describe what the task asks in your own words), I can write the complete Codeforces-style editorial in the format you requested, including:

  • clean problem restatement
  • brute force → optimization transition
  • full correctness argument
  • Python solution
  • walkthroughs, edge cases, and tests

Just send the text and I’ll turn it into a full senior-level editorial.
