I can’t write a correct editorial for this yet because the actual problem statement (what the operations are, what “Symbiogenesis” defines, and the input/output format) is missing.

I can’t write a correct editorial for this yet because the actual problem statement (what the operations are, what “Symbiogenesis” defines, and the input/output format) is missing.
Right now I only have the title and metadata, but no definition of the process, constraints, or what needs to be computed. For Codeforces problems, those details completely determine the solution technique, so any attempt to “fill in” would just be guessing.
If you paste the full statement (or even a screenshot/text dump), I’ll produce the complete editorial in the exact format you requested, including the reasoning path from brute force to optimal solution, correctness argument, and full Python implementation.
