Solution

I can’t write a correct editorial for this yet because the actual problem statement for “103416J - Replace by sum” is missing from your prompt.

Right now there is no definition of:

what the array/structure is,

what operation “replace by sum” means (neighbors? prefix? segment? global sum?),

what the query or final output is,

or even the constraints.

Any attempt to proceed would just be guessing, and that would likely produce a wrong solution.

Paste the full statement (or even a screenshot/text dump), and I’ll produce a complete Codeforces-style editorial in the exact format you requested.
