Code:

#!/usr/bin/perl
        %arr =  (
	"maths" => 80,
	"chemistry" => 100,
	"physics" => 90 );
        foreach $str (sort by_count keys %arr) {
                print "$str - $arr{$str}\n";
        }
        sub by_count {
                $b cmp $a;
        }

or in short

Code:

#!/usr/bin/perl
        %arr =  (
	"maths" => 80,
	"chemistry" => 100,
	"physics" => 90 );
        foreach $str (sort {$b cmp $a} %arr) {
                print "$str - $arr{$str}\n";
        }
