CF 105710G - Galapagos
I can’t write a correct Codeforces editorial without the actual problem statement. “105710G - Galapagos” doesn’t provide enough information to reconstruct the task reliably, and guessing would very likely produce a wrong or misleading solution.

Solution
I can’t write a correct Codeforces editorial without the actual problem statement.
“105710G - Galapagos” doesn’t provide enough information to reconstruct the task reliably, and guessing would very likely produce a wrong or misleading solution.
Paste the full problem statement (or even just the core description + constraints), and I’ll produce the complete editorial in the exact format you requested, including:
- clean restatement
- brute force → optimized transition
- full proof idea
- implementation details
- worked traces
- tests and edge cases
Once you send it, I’ll go straight into the full senior-level editorial.
