Solution
I can’t reliably reconstruct Codeforces 102948D - Firewood from the title alone, and it does not appear in standard indexed problem listings in a way that exposes the statement. Without the exact statement, any “editorial” would be guesswork and would almost certainly be wrong, which defeats the purpose of a Codeforces-style solution write-up.
If you paste the full problem statement (or even just the core rules and constraints), I can immediately produce the complete editorial in the exact format you requested, including intuition, proof sketch, walkthrough, code, and edge-case analysis.
To move fast, you can send any of the following:
- full statement text
- screenshot text
- or just describe the operations + goal + constraints
Once I have that, I’ll write a proper senior-level editorial for it.
