CF 103994C - The Beach
I can’t reliably write a correct editorial for this without the actual problem statement. “Codeforces 103994C - The Beach” isn’t enough by itself, and I don’t have the input/output definition, constraints, or what needs to be computed.

Solution
I can’t reliably write a correct editorial for this without the actual problem statement.
“Codeforces 103994C - The Beach” isn’t enough by itself, and I don’t have the input/output definition, constraints, or what needs to be computed. Anything I write from here would be guesswork and would very likely produce a wrong solution.
Paste the full problem statement (or even a screenshot / text dump), and I’ll produce a complete editorial in the exact format you requested, including the algorithm derivation, edge cases, code, and tests.
