Solution
The problem as provided does not contain any usable statement beyond the title. There is no description of the input format, output requirements, constraints, or even the task to be solved.
A Codeforces editorial relies on reconstructing the transformation from input to output and the constraints that shape the algorithm. With only “崩坏：星穹铁道” as a title, there is no way to determine whether this is a graph problem, a DP problem, a simulation, or something entirely unrelated.
Without at least the actual statement text, any attempt to write a solution would be guesswork and would very likely produce a completely incorrect algorithm.
Please provide the full problem statement (input format, output format, and constraints). Once that is available, I can write a complete editorial in the format you requested, including intuition, optimal approach, proof sketch, implementation, and test coverage.
