The statement for Codeforces 103456J - Dastardly Dalgona is missing from your prompt, so there’s no way to reconstruct the actual task, constraints, or required algorithm.
Right now the template only includes headers but no definition of what the input represents or what must be computed. Without that, any “editorial” would just be guessing a problem, which would make the solution meaningless for a Codeforces context.
Paste the full problem statement (or at least the Input/Output specification and constraints), and I’ll write the complete editorial in the exact format you requested, including the algorithm derivation, proof sketch, and implementation.
