I have a script that groups bunch of lines and prints in paragraphs. I am trying to remove duplicates while printing those paragraphs. Here is my code-

Original code that prints duplicate paragraphs while called- 
for my $list (@lists) {
    printGroups($list->{groups}, %group);
    print $list->{line};
    print "\n";
}

Print only uniq paragraphs- 
sub uniq {
    my %seen;
    grep !$seen{$_}++, @_;
}

for my $list (@lists) {
    my @filtered = uniq(@lists);
    printGroups($filtered->{groups}, %group);
    print $list->{line};
    print "\n";
}

But's it's not working and gives error- undefined value as an ARRAY.... Please let me know if you see anything lacking
