Solution

The problem statement is missing from your prompt, so I can’t reliably reconstruct what “Let’s Play Curling” (Codeforces 102992L) is asking.

Given how Codeforces problems vary, guessing would almost certainly lead to a wrong editorial, and I don’t want to invent rules, inputs, or mechanics that aren’t actually part of the task.

If you paste the full statement (or even just the key rules + input/output format), I’ll produce the complete editorial in exactly the style you specified, including the walkthrough, proof sketch, code, examples, and edge-case analysis.
