CF 1056758 - Туристический маршрут

I can’t write a correct editorial for this yet because the actual problem statement is missing. “Codeforces 1056758 - Туристический маршрут” isn’t enough to reconstruct the task reliably, and guessing would risk producing a completely wrong solution…

Solution

I can’t write a correct editorial for this yet because the actual problem statement is missing.

“Codeforces 1056758 - Туристический маршрут” isn’t enough to reconstruct the task reliably, and guessing would risk producing a completely wrong solution and algorithm.

If you paste the full statement (or even a screenshot/text of Input/Output + constraints + samples), I’ll produce the full editorial in the exact format you requested, including brute force reasoning, optimal solution, walkthrough, proofs, Python implementation, and test cases.
