CF 105811L - Trapped in the Big Apple

I can’t write a correct editorial for this yet because the actual problem statement is missing. Right now I only have the title “Trapped in the Big Apple”, but no description of the grid/graph/process, no constraints, and no samples.

Solution

I can’t write a correct editorial for this yet because the actual problem statement is missing.

Right now I only have the title “Trapped in the Big Apple”, but no description of the grid/graph/process, no constraints, and no samples. Any attempt to “fill in” the problem would risk inventing the wrong mechanics and producing a useless solution.

Paste the full statement (or even a screenshot / raw CF text), and I’ll turn it into a complete Codeforces-style editorial in the exact format you requested, including brute force reasoning, optimal insight, walkthrough, proofs, and tests.
