Solution

The problem statement is missing from your prompt, so I don’t have enough information to write a correct editorial.

“Codeforces 103109J - Luigi’s Mansion” alone isn’t sufficient to reconstruct the task reliably, and guessing would lead to an incorrect solution and misleading explanation.

Please paste the full problem statement (or at least input/output format and constraints), and I’ll write the complete editorial in the exact style you requested.
