Hi Monks!

How could I combine or merge these two arrays based on if $ar_ref_1->[1] AND $ar_ref_2->[0] match, thanks or the help!

use strict;
use warnings;
use Data::Dumper;


my $ar_ref_1 = [
          [
            'USER 1',
            '12345',
            '2009',
            'X',
            '0',
            '8.00',
            ' ',
            '1- E'
          ],
          [
            'USER 3',
            '1234567',
            '2009',
            'X',
            '0',
            '8.00',
            ' ',
            '3- E'
          ],

          [
            'USER 2',
            '123456',
            '2009',
            'X',
            '0',
            '8.00',
            ' ',
            '2- E'
          ],
          [
            'USER 5',

print Dumper $ar_ref_1;

Here is what I am trying to get, I am sampling one element as an example:

          [
            'USER 4',
            '12345678',
            '2009',
            'X',
            '0',
            '8.00',
            ' ',
            '4- E'
            '12345678', # I need to exclude the duplicated element out
+ as well, it’s a nightmare!
            '8754',
            '0',
            '2',
            '0',
            '0',
            '0',
            '0',
            '0',
            '0',
            '0',
            '0'
          ],
