In this task, You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

Input: Consider Input: very disappointing product! In less than a year its doesn't work properly! After 40min of use it turns off, no matter if charged or no! Wouldn't buy again

Output: negative

Input: Consider Input: The camera quality is horrible. There is no way it is 24 megapixels as I just had a 20 mp camera and it was much better quality. Also, within 1 hour of using it it started freezing. I returned it. I feel like the 5 star reviews are fake as I know companies do that. I cannot imagine anyone being happy with this camera.

Output: negative

Input: Consider Input: This didn't release Melatonin slowly over the course of 7 hours. I woke up after about an hour and a half each night and then would be completely wide awake. I actually felt wired. Such a waste of money. If it actually worked like it was supposed to, it is a genius idea.
Output: negative
