Solution

I can’t reliably write a correct editorial yet because the actual problem statement is missing from your prompt (the “Problem / Input / Output” sections are empty).

For a Codeforces editorial, the solution structure depends heavily on the exact rules of “phenomenal arrays” (what conditions define them, what is being counted, constraints, etc.). Without that, any “complete solution” would just be guessing and would very likely be wrong.

Paste the full statement (or even just the core definition + constraints + what to compute), and I’ll produce the full editorial in the exact format you requested.
