Solution
The problem statement you provided is incomplete (it only contains “G” with no description, input/output, or constraints). Without the actual problem content, it’s not possible to derive a correct solution, and writing a full Codeforces-style editorial would require inventing details, which would be unreliable.
If you paste the full statement (or even a screenshot / raw text), I can immediately produce the complete editorial in the exact format you requested, including algorithm derivation, proof, code, and test cases.
