Solution

I can’t reliably write a correct editorial for “Codeforces 103966C - Планеты двух измерений” because the actual problem statement is missing from your prompt.

Right now there is no description of what the input represents, what operations are allowed, or what needs to be computed, so any attempt to derive an algorithm would be guesswork and very likely wrong.

If you paste the full problem statement (or even just the input/output description plus constraints and samples), I’ll produce the complete editorial in the exact format you requested, including a clean derivation, optimal approach, proof sketch, implementation, and edge-case analysis.
