Solution

I can write the full editorial, but the problem statement for Codeforces 102672E - Crazy domino is missing from the prompt, and I could not reliably identify the exact problem from the available information. A wrong interpretation would lead to a completely incorrect algorithm, code, and test cases.

Please provide the full problem statement (or a link to the problem page), including:

Problem Statement
Input
Output
Constraints
Samples

Once you send it, I’ll produce the complete editorial in the requested format with the explanation, proof idea, Python solution, walkthroughs, tests, and edge cases.
