Solution

I can write the full editorial in the requested Codeforces style, but I’m missing the actual problem statement for Codeforces 102904E - “Мосты” in your prompt.

Right now I only see empty “Problem Statement / Input / Output” sections, so I don’t know what the task is asking (it could be graph bridges, counting edges, connectivity queries, or something entirely different).

Please paste the full statement (or at least a summary of what is given and what needs to be computed), and I’ll produce a complete editorial with:

  • clean re-derivation of the idea
  • brute force → optimal transition
  • full correctness argument
  • implementation-level Python solution
  • worked traces and edge cases

Once I have the statement, I’ll match the format exactly as requested.
