Solution
The problem statement for Codeforces 103994I - Make Nonzero Sum (hard) is missing from your prompt, so I don’t have the actual rules, inputs, or required output to base an editorial on.
Right now I’d be guessing the entire task, which would produce a misleading solution rather than a correct one.
Paste the full statement (or even a screenshot/text dump), and I’ll produce the complete editorial in the exact style you specified.
