Dear Monks,

am writing a simple substitutes program where both parameter of substitute are stored in variables 

#!/usr/local/bin/perl

$string = '10 09';
$regex = '(\d+) (\d+)';
$replace  = '$2 $1';

$string =~ s/$regex/$replace/;
print "$string \n";

-----------------------

When i execute that, it gives me the following output 
# ./test.cgi
$2 $1
