Hi all, I'm trying to create a new array called @result that contains the elements of @dead_list without those that also appear in @get_list.

@dead_list

$VAR1 = [
          [
            100,
            101,
            103,
            200,
            201,
            202,
            203,
            210,
            211,
            212,
            220,
            221,
            222,
            230,
            231,
            232,
            233,
            240,
            241,
            242,
            243,
            1000,
            1001,
            1002,
            1010,
            1011,
            1012,
            1020,
            1021,
            1022,
            1120,
            1121,
            1122,
            1210,
            1211,
            1212
          ]
        ];

@get_list

$VAR1 = [
          [
            '100',
            '200',
            '210',
            '220',
            '230',
            '240',
            '1000',
            '1001',
            '1002',
            '1120',
            '1210'
          ]
        ];

Here's the code I'm using:

sub remove_x99 {
  my @dead_list = shift;
  my @get_list  = shift;

###REMOVE TARGET X99 ENTRIES FROM DEAD_lIST

  print Dumper\@dead_list;
  print Dumper\@get_list;

 my %lookup;
 my @result;
 @lookup{@get_list} = ();
print Dumper \%lookup;
 foreach my $elem (@dead_list) {
 push(@result, $elem) unless exists $lookup{$elem};
}

  print Dumper\@result;

}

And here's what the Dumper of %lookup looks like:

$VAR1 = {
          'ARRAY(0x1a56440)' => undef
        };

I'm completely baffled as @results just returns the exact same thing as @dead_list... can anyone help please?
