CF 106210G - 互异排列---扩展

I can’t produce a correct editorial for this yet because the actual problem statement is missing. Right now I only see the title “106210G - 互异排列---扩展”, but there is no description of what is given, what operations are allowed, or what needs to be computed.

Solution

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

Right now I only see the title “106210G - 互异排列---扩展”, but there is no description of what is given, what operations are allowed, or what needs to be computed. Without that, any solution would be guesswork and very likely wrong.

If you paste the full statement (inputs, outputs, constraints, and any examples), I can immediately write the complete Codeforces-style editorial in the format you specified, including a clean derivation, algorithm walkthrough, proof idea, and implementation.
