create list of combinations

[vicens]

Hello,

I'm trying to create a list of all possible combinations of 1 array (2D). I have 3 elements/row:

Array:

a   b  c

1   2  3

A  B  C

*   +  {

Result:

a  a  a  a  a  ...

1  1  1  1  1  ...

A A  A  B B ...

*  +  {   *   + ...

Any idea?

Thank you.

Test size of each dimension and use the rotate array primitive.

Have fun!

hmm, maybe rotate is not the best idea.. here's a quick throw in for if you have just 2 sets of characters, hope it inspires you.

thank you,

By the way, if you want to be able to handle any number sets of chars, you will have to create a recursive algorithm, I think.
