if you take a closer look to data and result you will see that the relations are the same..
e.g.
A->[1, 2, 3, 4, 5, 6, 7]
is still given. enumerating CAN be the first step of the approach to get an easier comparison.. 
[1] => StringA
[2] => StringB
...
[A] => [1, 2]
[B] => [2]

But as i want to print that to an file, StringB will be there twice. e.g. StringB is equal to a data volume of 3gb. the file will be 6gb. for that i want to print this: 
[A]    => [1]
[A, B] => [2]
