Solution

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

Right now I only see the title “102893D - Multiple Subject Lessons” but no description of:

what the input contains, what decisions we’re making, or what the output should represent. Without that, any solution would be guesswork and very likely wrong.

Paste the full statement (or even a screenshot / raw text), and I’ll produce a complete editorial in the exact format you requested, including the algorithm walkthrough, proof idea, implementation, and test cases.
