Solution
I can’t reliably write a correct Codeforces-style editorial here because the actual problem statement for “1040351 - Время в школе” is missing from your prompt.
Right now I don’t know what the input represents, what needs to be computed, or even the constraints, and guessing would very likely produce a completely wrong solution and misleading explanation.
If you paste the full statement (even in Russian), I’ll turn it into a proper editorial in the exact style you requested, including a full derivation, optimal approach, walkthrough, code, and edge-case analysis.
