Hi everyone, I'm not an expert Perl programmer and I'm trying to sort a
hash.
I know how to sort it by it's keys, but this time it should be sorted by its
values.

So if I have

%hash = (
Apples => 1,
apples => 4,
artichokes => 3,
Beets => 9,
);

then it should be sorted and printed in this way:

Beets 9
apples 4
artichokes 3
Apples 1

Can anyone help me with this problem?

Thanks

And if you don't know how to do that, it's good idea to look it up,
don't you think?

perldoc -f sort

using variable number of spaces make the whole thing very complicated.
yet. if the number of spaces should be the same, you simply:

for my $sKey (sort { $hash{$b} <=> $hash{$a} } keys %hash) {
printf("%s : %u\n", $sKey, $hash{$sKey});
}
