Solution

I can write the full editorial in exactly that format, but I’m missing the actual problem content.

The statement section is empty in your prompt (“## Problem Statement / Input / Output” have no details), so I don’t know what “Even Adjacent Product” is asking us to compute.

Please paste the full Codeforces 103828J problem statement (or at least a clear paraphrase of what the task is, including input/output and constraints). Once I have that, I’ll produce the complete editorial in the required structure and style.
