Hello fellow monks,

I am using the following code to populate a hash with a key and an array of values 

$construct{$record->[1]}{$record->[2]} = 0;
    
foreach my $key (keys %construct) {
    $construct{$key} = [keys %{$construct{$key}}];
}

my %TEST;

while ((my $key, my $value) = each %construct) {
    my @values = @$value;
    $TEST{$key} = \@values;
}

How can I perform work on each of the values (i.e. maybe a join) and then print the key with its corresponding list of values?

Thanks
