My first post, so please excuse any sins I may commit ....

I have an array whose values consist of comma separated lists of 3 items(country,city,state).
I want to split each of these values, and put the results into 3 separate arrays (@countries,@cities,@states), and then make the values in those arrays unique.

Here is my (obvious) solution:
 for my $location (@locations){
        next if ($location eq 'HEADING');
        
        my ($country,$state,$city) = split /,/, $location;
        push @countries, $country;
        push @states, $state;
        push @cities, $city;
 }
 @countries = uniq @countries;
 @states = uniq @states;
 @cities = uniq @cities;

I'm looking for a cleaner, more readable approach to the task. Thanks!
