Re^2: Minimize Hash Key Value Combinations

thank you! that was my firt approach.. just use the strings as keys e.g.:

1 => A, B, C
2 => A, B, D
3 => C
[download]

but it leads to the same problem.. the result should be this:

1, 2 => A, B
2    => D
1, 3 => C
[download]

$perlig =~ s/pec/cep/g if 'errors expected';
