I am unable to answer my own question due to not enough reputation. The question is:
I think if I am not allowed to answer the question then it will mislead someone because the answer I have accepted is wrong one and there are no other correct answers.
So is it good to leave as it is?
I think I made the mistake in hurry to accept it. Now I know the answer and want to post it, but the system does not allow to submit due to not enough reputation.
