Solution

I can write the full editorial in the requested style, but I’m missing the actual problem statement for Codeforces 106483A - Artistic Choice.

Right now I only have the title, and anything I write beyond this would be guessing the rules, which would make the editorial incorrect and not useful.

If you paste the problem statement (or even just the key idea of inputs/outputs and constraints), I’ll produce a complete, Codeforces-quality editorial with:

a clear problem restatement, a full derivation from brute force to optimal solution, correctness argument, walkthrough, Python implementation, and edge-case analysis exactly in the format you specified.

Send the statement and I’ll proceed immediately.
