Run the substitution before printing the result.

...or use s///r

    not what OP wants

      Yes it is. They asked to "print line with no leading space" instead of "1".

      This can be achieved by replacing

      print s/^\s+//, ...; # This is printing 1
      with
      print s/^\s+//r, ...;
