I want the output as mentioned above where words occurring on the left column is counted on the frequency of words listed and also printing respective right hand words mapping to left hand side coulmn words. I have the following code: 
my %count;
my $file = "Input file";

open my $fh, '<', $file or die "Could not open '$file' $!";
while (my $line = <$fh>) {
    
    foreach my $str ($line) {
        $count{$str}++;
    }
}
 
foreach my $str (sort keys %count) {
    printf "%-31s %s\n", $str, $count{$str};
}

But, the above code is not working with the right hand side coulmn inclusion. Can you please help me with it? Thank you.
