Solution

The prompt is missing the actual problem statement for “Codeforces 102979I - Integer Array Shuffle”, so there is not enough information to reconstruct the task, constraints, or required transformation. Without that, any editorial would be guesswork and would very likely be incorrect.

If you paste the full statement (or even just the input/output description plus constraints and samples), I can produce the complete editorial in the exact format you specified, including the algorithm derivation, proofs, Python solution, and edge case analysis.
