Solution

I can write the full editorial in the requested style, but I’m missing the actual problem statement for Codeforces 104896B - Integral Array.

That gym/contest ID isn’t enough to reliably reconstruct the task, and guessing would almost certainly produce a wrong solution and misleading explanation.

Please paste the full problem statement (or at least the input/output description and constraints). Once you do, I’ll produce the complete editorial with:

clean re-derivation of the key idea
brute force → optimization progression
correctness argument
full Python solution
worked traces, edge cases, and tests

Just send the statement and I’ll proceed.
