Hi,
I have a problem using Tie::IxHash.
My question is how can I sort the hash
by value in descending order.
I tried this to get the descending order,
but doesn't seem to work:
__BEGIN__
my %hash =(
'1-1' => 3,
'2-3' => 2,
'2-2' => 1,
'1-2' => 6,
'1-3' => 3
);
my $t = Tie::IxHash->new(%hash);
$t->SortByValue; # ascending, ok!
$t->$hash{$b}<=>$hash{$a}SortByValue; #tried this but doesn't work
__END__
Can anybody advice how to go about this?
Thanks beforehand.
Regards,
Edward WIJAYA
