Solution
I can’t reliably write a correct editorial for this yet because the actual problem statement is missing from your prompt.
“Codeforces 106475F - Котик и светофоры” could correspond to multiple archived contest drafts, and without the full description (rules of the traffic lights, what the cat does, input/output definition, constraints), any solution would be guesswork. That would defeat the purpose of a serious editorial.
If you paste the full statement (or even just the key parts: what is given, what needs to be computed, constraints), I can produce a complete senior-level editorial in the exact format you requested, including derivation, proof, implementation, and test coverage.
