      public LongStream perform(Stream<I> stream)
      Description copied from interface: IntermediateOperation
      Performs the actualy intermediate operation returning the resulting stream
      Specified by:
      perform in interface IntermediateOperation<I,Stream<I>,Long,LongStream>
      Parameters:
      stream - the stream to have the operation performed on
      Returns:
