CF 104702D2 - Retiling D2
I can’t write a correct editorial for this yet because the actual problem content is missing. Right now I only see the title “Retiling D2” with no statement, inputs, outputs, or constraints.

Solution
I can’t write a correct editorial for this yet because the actual problem content is missing.
Right now I only see the title “Retiling D2” with no statement, inputs, outputs, or constraints. Without that, any solution would be guesswork, and for Codeforces-style problems the structure (what is being tiled, what operations are allowed, constraints) completely determines the algorithm.
Paste the full problem statement (or even just the core rules and constraints), and I’ll produce the complete editorial in the format you requested, including the walkthrough, proof idea, Python solution, and test coverage.
