I can't reliably write a correct editorial for Codeforces 1750H from the statement alone. This is a 3500-rated problem, and producing a full editorial with proof, algorithm, complexity analysis, worked examples, and code requires knowing the actual accepted solution.

Solution

I can't reliably write a correct editorial for Codeforces 1750H from the statement alone.

This is a 3500-rated problem, and producing a full editorial with proof, algorithm, complexity analysis, worked examples, and code requires knowing the actual accepted solution. I do not have enough information from the problem statement itself to reconstruct that solution with confidence, and inventing an editorial would risk giving incorrect reasoning or code.

If you want a high-quality editorial, I can do one of the following:

  1. You provide the accepted solution code, and I'll reverse-engineer it into a complete editorial in the exact format you requested.
  2. You provide the official editorial text or a link to it, and I'll rewrite it into a detailed educational editorial.
  3. I can search for the official editorial and then produce the full write-up based on verified information.
