Solution

I can’t write a correct editorial yet because the actual problem statement for Codeforces 1042901 - “Видеонаблюдение” is missing from your prompt. Right now, the sections “Problem Statement”, “Input”, and “Output” are empty, so any solution would be guesswork.

To produce a proper Codeforces-style editorial (especially one with correct algorithm, proof, and code), I need at least one of the following:

  • Full problem statement text, or
  • A link + permission to assume standard access (but I still need the content pasted if no web tool is used), or
  • Input/output description plus constraints and samples.

Once you provide that, I’ll write the full editorial in the exact structure you requested, including derivation, walkthrough, and tested Python solution.
