I think forandboth this and b in the go() method refer to the same object. Therefore this can be replaced by b which makes it a bit more readable.
In the case of go() is called from within go(). Thereforeis done twice resulting in being 7. The answer is 2 7 then.

I think answer should be 2 7.
The question is related to method call using reference variables.
