Solution
The problem statement for Codeforces 103560B - Ландшафтный дизайн is missing from your prompt, so there is no way to correctly reconstruct the logic, constraints, or required output.
For a Codeforces editorial, the exact rules of the task are not optional, since even small differences (grid vs tree, minimization vs counting, constraints scale) completely change the algorithm and complexity class.
Please paste the full problem statement (or at least input/output description plus constraints and sample I/O). Once you provide that, I’ll write the complete editorial in the exact format you specified, including the walkthrough, proofs, code, and edge-case analysis.
