All I could get is to use permutations and concatMap. But it looks really ugly. On Fri, Mar 12, 2010 at 2:09 PM, Casey Hawthorne <caseyh@istar.ca> wrote:
This sounds like homework.
Think in abstract terms what you want to accomplish.
Start with the simplest case first, usually the base case.

Hi, For example, I have this: list1 = [a, b, c] list2 = [d, e, f] list3 = [g, h, i] Now I want: [ [(a, d, g), (b, e, h), (c, f, i)] , ... ] -- a list that contains all the combinations. How to do it pretty? Thanks. -- Regards, Casey
