Solution

I don’t have the actual statement for Codeforces 105584H - Blocking the Way, and without it I can’t reliably reconstruct the problem, constraints, or intended solution.

Right now the editorial template is asking for a full solution narrative, but the core ingredient is missing: what the grid/graph/input actually is and what “blocking the way” refers to.

If you paste the problem statement (or even a rough version), I can immediately produce the full editorial in the exact format you specified, including brute force reasoning, optimal insight, code, proofs, and test cases.
