An easier way to find the highest hash value

without looping through all of them

Is there an easy way of finding out which key in my hash has the highest value. I'm currently going through each one by one and comparing them.

I know there are lots of Perl tricks and wonder if there is one for this.

As an example, say:

$hasharray{"turnips"} = 9
$hasharray{"swedes"} = 3
$hasharray{"carrots"} = 95

What is the easier way to find carrots?

you will have to go through all the hash keys to find the highest value, that is a given. But you can use sort to do the dirty work:

my @sorted = sort {$hasharray{$b} <=> $hasharray{$a}} keys %hasharray;
print $sorted[0];
