Solution

I could not reliably retrieve the exact statement of Codeforces problem 103358A - “Работа из дома” from the available archive sources. Without the precise statement, writing a correct, fully rigorous editorial would risk inventing problem details, which would defeat the purpose of a high-quality competitive programming explanation.

If you paste the full problem statement (or even just the input/output description), I will produce a complete editorial in the exact format you requested: full derivation, optimal insight, walkthrough, proof sketch, Python solution, and edge-case analysis.

Once you share it, I can also align the solution style with typical Codeforces A-level structure and ensure the reasoning is something you can reuse for similar problems.
