Solution
The problem statement is missing from your prompt, so there is no way to reconstruct the intended task, constraints, or required algorithm.
Codeforces problems with the same format can range from simple graph traversal to heavy data structure or offline query problems, and the editorial structure depends entirely on what “Subway” is actually asking. Without the actual definition of the subway system, input format, and required output, any solution would be a guess rather than a correct editorial.
If you paste the full problem statement (or even just the input/output description and constraints), I can immediately produce a complete Codeforces-style editorial in the exact format you requested.
