I have small problem that could be solved with a mathematical calc, but I don't know how.
I have six variables String , and I must find all the combination between them.
Obvisually , in every combination, the same string can't appear!
In these example, I tried to find the combinations for the first column. i don't know if it's right.
white, yellow , red, black, blue
white, yellow white, yellow , red white, yellow , red,black, white, yellow , red,black, blue, white, red, black, blue white, black , blue white, blue white black,
... and so on...
How can i have a algorithm to calc this stuff?
