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.

Example Input: It just straight out does not work I put the right batteries in it and it does absolutely nothing but but then again it wasn't that expensive so so I kind of figured it wouldn't anyway
Example Output: negative

Example Input: So bad. I feel like the dishes would’ve been more clean if I used nothing. Dishes came out dirty and filmy every time. Couldn’t even tell if I ran the dishwasher or not and was having to rewash every dish.
Example Output: negative

Example Input: This brush is the perfect brush for our curly haired toddler. My 3 year old has very long hair for her age and it gets tangled very easily. She had started to cry when we needed to brush her hair after bath time because her baby comb would snag on her curls and hurt. This multi pack is perfect cause now I have one for the diaper bag. It's small enough to stick in our swim bag without having to haul our whole restroom with us. The brush gently moves around my daughter's hair, and never pulls her head back (like my loving mother used to do to me!). No More Tears!!
Example Output:
positive
