removing last element of a list(scheme)

Question

So I have to remove the last element of a list in scheme.

For example, let\'s say I have a list (1 2 3 4). I need to return:

(1 2 3)
         


        

Answer 1

I would do a recursive function that goes down the list and attaches the element (using cons) if the element after it is not the last, and appends nothing if it isn't.

I haven't done scheme for years though so that's as far as I can go.

Someone can run with how to implement it (unless it's homework then they probably shouldn't!)
