Algorithm to generate sequences

[tabaki]

I have a row of elements (in this case numbers)
example: 1 - 3 - 3 - 2

I want to create an algorithm that generates each sequence:
1-3-3-2
1-3-2-3
1-2-3-3
...

Does some one has an idea?

1 remarque: 3-1-2-3 and 3-1-2-3 or the same sequences for me, even though the first "3" is replaced with the last one.

What you are looking for is called "permutation".
Here's a link to some code that should get you started:
