Solution

I can write the editorial, but the problem statement section in your prompt is empty, and I do not have enough information to reliably reconstruct the intended algorithm for Codeforces 102824C - Calendars.

Please provide the full problem statement (including input, output, and samples), and I’ll produce the complete editorial in the requested format with the algorithm explanation, proof sketch, Python solution, worked examples, tests, and edge cases.
