CF 106050H - Has a Unilestep ever existed?

I can’t write a correct editorial for this problem as-is because the actual problem statement is missing. Right now there’s no description of what “Has a Unilestep ever existed?” is asking, so I would have to guess the task, constraints, and intended solution.

Solution

I can’t write a correct editorial for this problem as-is because the actual problem statement is missing.

Right now there’s no description of what “Has a Unilestep ever existed?” is asking, so I would have to guess the task, constraints, and intended solution. That would very likely produce a completely incorrect editorial.

If you paste the full statement (or even a screenshot/text dump), I’ll write the full Codeforces-style editorial exactly in the format you requested, including the algorithm walkthrough, proof idea, code, examples, and edge cases.
