Hello monks, perl novice here. I've been using perl for under a week, our class has decided to do a 2-week crash course into the wonderful world of perl to complete our year. As such we were given a simple task (or so it seemed). Ask the user to enter 16 digits, then print those 16 digits out in 4 groups of 4 (IE: 1234 1234 1234 1234). So far I have managed to do this: 
use strict;
use warnings;

print 'Please enter your card number'
chomp($inp = <>);
$inp =~ s/(\d{4})(\d{4})(\d{4})(\d{4})/$1 $2 $3 $4/;
print $inp,"\n";

It didn't work and I want to see what I've done wrong and what I need to fix in order to reach my end goal. Thank You
