Ahhh! That again. I was thinking about using the representation. 
I should take a deeper
look at the documentation.

As far as my current understanding goes the shuffle will be done 
in place.
If I use the "representation" would that still hold, that is will 
I be able
to use the same char[] but in the shuffled form? (of course I 
will test that)

Thank you
