hey list. i stuck with gererating a wordlist from a changing
multidimensional array. each entry in the array contains a list with the
possible values.
You want a "cartesian cross product". And there's a module out there that
does just that: Set::CrossProduct.
http://search.cpan.org/~bdfoy/Set-CrossProduct-1.6/CrossProduct.pm
Sample use:
use Set::CrossProduct;
my $iterator = Set::CrossProduct->new(['a','b'],['c'],['d','e','f']);
my @wordlayout = $iterator->combinations;
@wordlayout will be an array of array references (like ['a','c','f']). To
turn them into strings, you could do:
my @wordlayout = map join("", @$_), $iterator->combinations;
any hints on how to solve this? probably using recursion but i got no
idea about it right now. and sorry for my bad english, hope i can make
my problem understandable.
It would be a fun exercise to do this on your own, and yes, recursion is
the most obvious way to do it.
