CF 103091D - Hedgehog Grid
I can’t reliably write a correct editorial for this yet because the actual problem content is missing. “Codeforces 103091D - Hedgehog Grid” isn’t something I can reconstruct safely from the title alone, and if I guess the rules (movement, scoring, constraints, etc.

I can’t reliably write a correct editorial for this yet because the actual problem content is missing.
“Codeforces 103091D - Hedgehog Grid” isn’t something I can reconstruct safely from the title alone, and if I guess the rules (movement, scoring, constraints, etc.), the editorial will very likely describe the wrong model and mislead readers.
Paste the full problem statement (or even just the key rules and constraints), and I’ll produce the complete editorial in the exact format you requested, including the algorithm walkthrough, proof idea, code, and edge-case analysis.
