Solution

The problem statement is missing from your prompt, so there isn’t enough information to correctly reconstruct or explain the task.

“An Array and Range Additions” is a common name used for multiple different Codeforces-style problems (difference arrays, segment trees, prefix updates, offline queries, etc.), and the correct editorial depends entirely on the exact operations, constraints, and queries.

If you paste the full statement (or even just the input/output description and constraints), I can write the complete editorial in the exact format you requested, including algorithm derivation, proofs, code, and test cases.

Send the statement and I’ll continue from there.
