Solution

I can write the full Codeforces-style editorial, but I’m missing the actual problem statement for 103548B - “Ремонт дороги”.

Right now there’s no description of:

  • what the road structure is,
  • what operations are allowed,
  • what needs to be computed,
  • or the constraints.

Without that, any “solution” would just be guesswork, and I don’t want to fabricate a wrong algorithm.

Paste the full statement (or even a screenshot text dump), and I’ll produce the complete editorial in the exact format you specified, including brute force reasoning, optimal insight, proof, code, tests, and edge cases.
