Hi, Given a 2D array, in wich rows may have a different number of defined elements. How to store, in a second table, all possible combinations of row1 elements with row 2 elements with row 3 elements, etc. (i.e. 1 element per row).

Given: 

my @AoA1 = (['a','b','c'],
           ['d','e',''],
           ['f','g',''],
           ['h','','']);

[download]
Put combinations into AoA2: 
@row1 = qw(a d f h);
@row2 = qw(b d f h);
@row2 = qw(c d f h);
@row2 = qw(a e f h);

[download]
and so on...

Thanks, regards.
