Solution

I can write the full editorial, but I’m missing the actual problem content.

The statement section you provided for “Codeforces 103428H - city safety” is empty, so there’s no definition of:

what the graph/array/city structure is, what “safety” means, what operations or queries exist, or what needs to be computed.

To produce a correct editorial (especially with algorithm walkthroughs, edge cases, and tests), I need at least one of the following:

  1. Full problem statement text
  2. Input/output specification plus constraints
  3. A link or pasted statement content
  4. Even a rough paraphrase of the task

Once you provide that, I’ll write the complete editorial in the exact style you requested, including a derivation of the optimal solution, proof sketch, and full implementation.
