I figured it out in the end.

I like this kata because it taught me not to mutate the inputs, now i try keep this in mind when solving other kata.

I have no idea how this works for the arrays with only one item in them.

Im so confused.
I made a new list and mutated that...didnt work.
So there is a way to remove the lowest number without changing the original list.
My only guess is u get the minimum number seperately and do something with it.
