You can see that all of them downvoted, this is not the case, but the downvoter should provided a correct answer or provided a comment for one answer at least.
I knew downvoting is also important but providing correct answer is also very important in order to distinguish between correct and incorrect answers.
I hope some one help us, why all answers are downvoted without any comments or a correct answer. Currently, one answer is also accepted with had two downvotes.
