Hi,
Is there an easy way to get all the unique elements of an array? i.e. is there some module or function that does that sort of thing?
There are excellent modules to handle this, but it's also pretty simple to roll your own in most cases:
sub unique { # see title of this message for usage
my @all = @_;
my %seen;
$seen{$_}++ foreach @all;
return keys %seen;
}Hope that helps.
