Solution

I can’t write a correct Codeforces editorial for “105876B - Crazy Permutation” without the actual problem statement.

Right now the prompt is missing the only thing that determines the solution: what the permutation represents, what operations or constraints are involved, and what is being asked to compute. If I tried to reconstruct it from the name alone, I’d end up hallucinating a problem and producing a misleading editorial.

Paste the full statement (or even a screenshot / raw text), and I’ll turn it into a complete, Codeforces-style editorial in the format you specified.
