This doesn't make a lot of sense to me, but I assume you have a purpose
in mind for this. What is the purpose? Perhaps it will help the
explanation if we know what it's for.

Does this mean the input is a list, ‘[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]’? Or
do you mean something else? What is the input?

That's three different lists. What is the input in each case? Under what
circumstances would you expect each one to be produced?
