Removing duplicate elements from an array

mkurtis has asked for the wisdom of the Perl Monks concerning the following question:

I did a supersearch, and found How can I display a unique array if it contains some repeated elements, but this doesn't work. I still get all kinds of duplicates. I have tried all kinds of hash keys and other things as well.

foreach $term(@inputs) {
@result = $words{$term};
push @results, @result;
}

undef @numbers{@results};
my @results2 = keys %numbers;
print "@results2\n";
[download]

This still allows duplicates, and also combines some of the array elements, I'm assuming from push.

Thanks

`my %unique; @unique{@dups} = (); my @uniq = keys %unique;` [download] If you want this data to be unique you might be better to use a hash in the first place. cheers tachyon	[reply] [d/l]

Figured it out, @result contained blocks of numbers, so $result didn't pull out individual ones. Had to split them. Now it works fine. Thanks	[reply]
