I need a functions which takes as argument a list of lists like this one:


and gives me a list of list with all the possible combinations like this one:


In this case there are only 2 combinations but if there was more than one
element in the other lists the results were much more.

I'm a little stuck in this simple problem.

First i was thinking in cartesian product but then i realized that i may
not be what i really need.

Any tip?

Many thx,

Nuno Santos
