CF 1049494 - Выбор столицы

I can’t write a correct editorial yet because the actual problem statement is missing. Right now I only see the title “Выбор столицы” (“Choosing a capital”), but there is no description of the graph, input format, constraints, or what needs to be optimized.

Solution

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

Right now I only see the title “Выбор столицы” (“Choosing a capital”), but there is no description of the graph, input format, constraints, or what needs to be optimized. Without that, any solution would be a guess, and for Codeforces-style problems that almost always leads to a wrong algorithm.

Paste the full statement (or even a screenshot / raw text), and I’ll produce the complete editorial in the exact structure you requested, including derivation, proof, Python solution, traces, and edge-case analysis.
