CF 102821E - Edge, Path, Number

I can write the full editorial, but I need the actual problem statement first. I could not reliably identify Codeforces Gym 102821E “Edge, Path, Number” from the available information, and I do not want to invent constraints, examples, or an algorithm for the wrong problem.

Solution

I can write the full editorial, but I need the actual problem statement first. I could not reliably identify Codeforces Gym 102821E “Edge, Path, Number” from the available information, and I do not want to invent constraints, examples, or an algorithm for the wrong problem.

Please paste the full statement (including Input, Output, constraints, and samples), and I’ll produce the complete editorial in the requested format.
