CF 105874H - The Beautiful City $\mathbb{S}$

I can’t reliably write a correct editorial for Codeforces 105874H without the actual problem statement. The number alone isn’t enough, and guessing would produce a misleading solution.

Solution

I can’t reliably write a correct editorial for Codeforces 105874H without the actual problem statement. The number alone isn’t enough, and guessing would produce a misleading solution.

Paste the full statement (or even a screenshot/text), and I’ll produce the complete senior-level editorial in the exact format you requested, including derivation, proof sketch, implementation, and tests.
