Solution
I can’t write a correct editorial for this specific problem yet because the actual statement is missing from your prompt.
Right now I only have the contest ID (“Codeforces 106373E1 - Оптимальный опенспейс - 2”), but no description of:
what the grid/structure is, what operations are allowed, what “optimal open space” means in this context, or what needs to be optimized.
For a Codeforces editorial in the style you requested, the exact mechanics matter down to small details. If I guess, I risk inventing a different problem and giving you a misleading solution.
Paste the full problem statement (or even a screenshot text dump), and I’ll produce a complete, structured editorial with:
a clean restatement, brute force vs optimal derivation, full proof idea, implementation, traces, and edge-case handling.
