Solution

I can’t reliably write a correct editorial for this yet because the actual problem statement for Codeforces 105940L - The Elephant and the Array is missing from your prompt.

That matters here more than usual because Gym-style problems with similar names often differ only in a small constraint or operation definition, and the solution technique depends entirely on those details. Without the exact rules of what the “array” operations are, what the elephant does, and what is being queried or optimized, any attempt would be guesswork and would very likely produce a wrong algorithm.

If you paste the full statement (or even just the operations + constraints + what needs to be computed), I’ll write the complete editorial in the exact style you requested, including a proper derivation, edge cases, and a tested Python solution.
