Solution

I don’t have the actual statement of Codeforces 104922I - Paired roads, so I can’t reliably reconstruct the problem or derive a correct editorial.

If you paste the full problem statement (or even just the input/output description and constraints), I’ll write the complete editorial in the exact format you specified, including derivation, algorithm walkthrough, code, and tests.
