Dear Monks,
I have this HoA reference. 

my $HoA_ref = {'GAT' => [2, ['ttt',-3,1],['ttc',-3,3],['ccc',-1,2]],
               'AAA' => [13,['aaa',-1,2],['atg',-2,2]], 
               'TTT' => [11,['tta',-2,1],['atc',-3,3]]
               };

# Need to print 'AAA' slice only coz have'13' as highest value

Would like to print *only* the top sorted Hash based on the zeroeth element of the value.
Sucht that it gives *only* 
AAA 13:
aaa,-1,2
atg,-2,2

I tried this function but of no avail: 
#namely how can I pick only the topmost with this subroutine
#besides some reference error that I encounter.

sub print_zHoA {
    my ($HoA) = @_;
    foreach my $mc (sort {$HoA{$a}[0] <=> $HoA{$b}[0]} keys %$HoA){
      print "$mc $HoA{$mc}[0]:\n";
      foreach my $i (0.. $#{$$HoA{$mc}}) {
        print "$$HoA{$mc}[$i]->[0],$$HoA{$mc}[$i]->[1],$$HoA{$mc}[$i]-
+>[2]";
       }
        print "\n";
    }
}

How can I go about it?
Thanks so much beforehand.
Regards,
Edward
