When using the cartesian product, and you have three collections, do you take two collections at a time OR all three together to calculate the product?
My question is if you have more than two collections, let's say A, B and C
A = {1,2,3} B = {4,5,6} C = {7,8} A x B x C {1,2,3} x {4,5,6} x {7,8}
Do you with the cartesian product calculate A x B, then B x C? And maybe A x C? Which means you take only two collections at a time.
OR
Do you take all three collections at the same time A x B x C?
