Solution

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

Right now I only have the title “Взрывоопасная лестница” (“Explosive staircase”), but no description of what the stairs do, what constitutes a “state”, or what needs to be computed. Any attempt to proceed would be guesswork and would very likely produce a completely wrong solution.

Please paste the full problem statement (including input/output format and constraints). Once you do, I’ll write the complete Codeforces-style editorial in the exact structure you requested, including the algorithm derivation, correctness argument, and a full reference implementation.
