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: Bought two of these mattresses for a bunk bed and they are terrible. You can see where the springs are and there is little to nothing separating them from the cover. Description lists 2" of total foam and there can't be more than a half inch. You get what you pay for but the description could atleast be correct.
Example Output: negative

Example Input: I need something to hold my new prescription glasses - I wanted to protect my Coach glasses and this was perfect. Double protection and great to toss in beach bag
Example Output: positive

Example Input: I was happy with this cover to begin with but after less than two months it has torn. I tried contacting Amazon and Leader Accessories about the two year warranty and each company tells me to contact the other. Communication with Leader Accessories is not good. No call back and email is lacking all professionalism.
Example Output:
negative
