Monks, I have this bit of code: 
 
use warnings;
use Data::Dumper;

my $counter = 3;

%hash = (
    a1_2 => 0.556,
    a1_3 => 0.345,
    a2_1 => 0.556,
    a2_3 => 0.125,
    a3_1 => 0.345,
    a3_2 => 0.125,
);

print Data::Dumper->Dumpxs([\%hash], [q{*hash}]);

for (1 .. $counter) {
    my @holder = ();
    my $outer = $_;
    
    for (1 .. $counter) {
        
        my $inner = $_;
        
        if ($outer == $inner) {
            
            next;
            
        } else {
            
            my $tracker = "a$outer\_$inner";

            foreach $key (keys %hash) {
                my $value = $hash{$key};
                if ($key eq $tracker) {
                    print "$tracker : $key : $value\n";
                    
                    push @holder, $value;
                    
                }
            }
        }
    }
    @holder_sorted = sort { $a <=> $b } @holder;
    print "@holder_sorted\n"; 
        # this works to sort the values, but
        # how do you sort the values while keeping track of the keys?
}

The comment in the code asks the question. But for clarity, I want to sort hash values, while keeping track of the keys. Ultimately I want to be able to determine which has the highest value, and then use the key that matches the highest value in another subroutine (not shown). I am stuck, any help/advice would be great!

thanks!
