Solution
The problem statement is missing from the prompt, so I can’t reliably reconstruct what “Coats of Paint” (Codeforces 103920D) is asking.
For a Codeforces editorial, even a small mismatch in interpretation changes the entire solution, so I’d need at least the full statement (or a link / pasted text / input-output description) to proceed.
If you paste it here, I’ll produce the full structured editorial in the exact format you requested, including:
- clean restatement in my own words
- constraint-driven reasoning
- brute force → optimization narrative
- full algorithm walkthrough with invariants
- Python solution
- worked traces, complexity table, and assert-based tests
Send the statement and I’ll continue immediately.
