CF 1059431 - Car Wash
I can’t write a correct editorial for that problem yet because the statement is missing. “Codeforces 1059431 - Car Wash” is not enough to reconstruct the rules reliably, and guessing would almost certainly produce a wrong solution and misleading reasoning.

I can’t write a correct editorial for that problem yet because the statement is missing.
“Codeforces 1059431 - Car Wash” is not enough to reconstruct the rules reliably, and guessing would almost certainly produce a wrong solution and misleading reasoning.
If you paste the full problem statement (or even just input/output description and constraints), I’ll produce a complete Codeforces-style editorial in the exact format you requested, including the optimal approach, proof sketch, Python solution, and edge case handling.
