Here's some quick test code I wrote up:
%songs = (
'Insomina' =>
{
'sales' => '9999',
'votes' => '1'
},
'Enter Sandman' =>
{
'sales' => '9998',
'votes' => '10'
},
'Bad Moon Rising' =>
{
'sales' => '9997',
'votes' => '9'
}
);
sub bysales { $songs{$b}{sales} <=> $songs{$a}{sales}; }
sub byvotes { $songs{$b}{votes} <=> $songs{$a}{votes}; }
# Print the best songs by sales
foreach $ditty ( sort bysales keys songs ) { print "$ditty\n"; }
# Print the best songs by votes
foreach $ditty ( sort byvotes keys songs ) { print "$ditty\n";
Of course, TMTOWTDI, as usual.
HTH!
