@aoaoh;

$aoaoh[0][0]{21} = 31;

$aoaoh[0][0]{22} = 31;

$aoaoh[0][0]{23} = 17;

for $k(0.. $#aoaoh) {

for $i(0.. $#aoaoh) {

for $val (keys %{$aoaoh[$i][$k]}) {

print "$val=$aoaoh[$i][$k]{$val}";

print "\n";
}}
}

output is

but i expect it to be

Please tell me where is this wrong.. Also how do i sort the values so that i get the output as

23=17

22=31

21=31 (if 2 keys have same value then key with higher value come first)
