I've posted an answer for this Question. Initially the question owner accepted my answer. But later based on comment requests from Felix Eve the question owner updated his question (instead of asking a new question).
So Felix Eve gave answer and question owner accepted. Is it valid? You can find those details more clearly form their comments.
Here I'm not really worrying about my lost reputation (-15) ;)
Here my answer seems invalid. So do I need to delete my answer or can I suggest question owner about this?
Please suggest me.
