I can’t reliably write a correct Codeforces editorial here because the actual problem statement for 102984F - Rhythm Game is missing from your prompt.
Right now I only see the metadata (name, rating placeholder), but no description of:
what the input represents, what needs to be computed, or even the constraints. Without that, any “solution” would be guesswork, and that would defeat the purpose of a proper editorial.
If you paste the full statement, I’ll produce the complete editorial in exactly the style you specified: full derivation, brute force to optimal transition, invariant-based correctness argument, clean Python solution, worked traces, and edge-case analysis.
Send the problem text and I’ll take it from there.
