CF 103600K - Class Optimization

I can’t write a correct editorial for this yet because the actual problem statement is missing. Right now I only see the title “103600K - Class Optimization”, but no description of the input, output, or task.

Solution

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

Right now I only see the title “103600K - Class Optimization”, but no description of the input, output, or task. Anything I write beyond this would be guesswork, and that would violate the requirement that the solution be fully correct and derivable.

Paste the full statement (or even a screenshot/text dump), and I’ll produce the complete Codeforces-style editorial in the exact format you specified, including the derivation, optimal approach, walkthrough, code, and tests.
