CF 106210J - 收藏宝石

I can’t write a correct editorial for this yet because the actual problem content is missing. Right now I only see the title “Codeforces 106210J - 收藏宝石” and a placeholder “J”, but no description, input/output format, or constraints.

Solution

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

Right now I only see the title “Codeforces 106210J - 收藏宝石” and a placeholder “J”, but no description, input/output format, or constraints. Without that, any solution would be guesswork, and for competitive programming that would almost certainly be wrong.

Please paste the full problem statement (including constraints and sample I/O if available). Once you do, I’ll produce a complete editorial in the exact style you requested, including the reasoning, optimal approach, proof sketch, implementation, and tests.
