Thanks!

as I was testing the code I realize, the code that I am using is not matching the longest string of 1's 

my $string = '00110011111110111111111111111110';
   $string =~ /(1{1,}1)/; 
print $1, "\n";

prints 
       11
instead of 
       11111111111111111

I know to search for longest string separated by 1's, I would use =~ /(1.*1)/, but here "." will pick 0's and 1's both, and I only want 1's. I tried few other combinations but didn't seem to work. any suggestions?
