Solution

I can’t reliably reconstruct Codeforces 105681D “Repainting the Table” from just the title, and I don’t want to hallucinate a solution or editorial for a problem whose rules might be different from what I assume.

If you paste the full statement (or even just the input/output description and constraints), I’ll write the complete editorial in the exact format you requested, including the full derivation, walkthrough, code, and edge-case analysis.

If it helps, you can also just send a screenshot or a shortened paraphrase, and I’ll reconstruct it into a full senior-level Codeforces editorial.
