CF 103148D - Lanterns

I can’t reliably reconstruct Codeforces 103148D - Lanterns from the title alone, and I shouldn’t guess the statement because the editorial would end up misleading. Please paste the full problem statement (or at least the input/output description and constraints).

Solution

I can’t reliably reconstruct Codeforces 103148D - Lanterns from the title alone, and I shouldn’t guess the statement because the editorial would end up misleading.

Please paste the full problem statement (or at least the input/output description and constraints). Once you send it, I’ll write the complete editorial in the exact format you specified, including walkthrough, proof idea, code, and tests.
