The statement you provided is incomplete, so it’s not possible to write a correct, problem-specific Codeforces editorial yet.
All we currently know is a single hint: “You can brute force this problem. Simulate what happens if Edward were to drop down at each pole.” That suggests a simulation over “poles”, but the actual mechanics are missing. We don’t know what a “pole” contains, how Edward moves between them, what defines a step, what the input structure is, or what exactly should be output.
Without those details, any attempt to fill in a full solution would be guesswork, and for this kind of problem that usually leads to an incorrect algorithm being written confidently but solving the wrong task.
If you can paste the full statement (especially the input format and movement rules), I can immediately produce the full editorial in the exact style you requested, including the brute force simulation and the optimized interpretation if one exists.
Right now, the only safe conclusion is:
The problem is a per-start simulation over a structure of “poles”, and the intended solution is to run a deterministic process from each starting position. But the transition rules are unknown, so neither the state space nor the termination condition can be defined.
Send the missing part and I’ll turn it into a complete Codeforces-quality editorial.
