Solution
I don’t have the actual statement of Codeforces 1055971 - “Полосатая раскраска” in your prompt, and the fields for input/output are empty. Without the problem definition, any editorial would be guesswork, and that would break the correctness requirement of what you’re asking for.
If you paste the full statement (or even just describe the rules of the coloring process and what needs to be computed), I can produce the complete Codeforces-style editorial in the exact format you specified, including the algorithm walkthrough, proofs, code, and test cases.
