I tried to pull out a signed /or unsgined number from string using regexp in perl.

       $str = "This string has a number +15 init ";

       regex : m/.*([\+|-](\d+)).*$/ #which works well for above said 
+string

but consider this case

      $str = "This  string has a number15 init";

      #i need to fix the above regex to work for avove string as well
