Solution

I don’t have the actual statement for “Codeforces 103719J - Rooks Defenders” in your message, so I can’t reconstruct the intended model, constraints, or solution without risking hallucinating the problem.

If you paste the full problem statement (or even just the operations + constraints), I’ll write the complete editorial in the exact format you specified, including the full derivation, algorithm, proofs, code, and tests.

If it helps, you can also just send:

  • input format
  • output format
  • constraints
  • what operations are involved (queries, updates, etc.)

and I can still produce a correct, self-contained editorial from that.
