Hi Allan,
How about sorting the hash keys by their value,
instead of inverting the hash?
my %presVocab = (
'nuclear' => 'nuculear',
'terror' => 'terra',
'horror' => 'horra'
);
my @keys_sorted_by_value = sort {
$presVocab{$a} cmp $presVocab{$b}
} keys %presVocab;
foreach my $key(@keys_sorted_by_value) {
print "$key => $presVocab{$key}\n";
}
Cheers,
David Iberri
