Solution

I can write the editorial, but the problem statement provided here is incomplete. The “Problem Statement”, “Input”, and “Output” sections only contain placeholders, so I do not have enough information to reliably explain the required algorithm, prove correctness, provide a Python solution, or create valid test cases.

Please provide the full statement for Codeforces 102788E - Black Box, including the actual input format, output format, constraints, and samples. I’ll then produce the complete editorial in the requested structure and style.
