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: After reading reviews, I thought I would order 2 sizes up. Normally I’m a L/XL, so I purchased a 2X figuring it would fit! To my surprise, the shirt was way too small. It fits my sister who is a size small. The material was not cotton as I thought, but 95% spandex. I’m very disappointed as the shirt is very cute. Instead of returning it, I gave it to my sister. I would recommend ordering 3 or more sizes up from what you normally wear.
Example Output: negative

Example Input: I own two of these drives, one operates perfectly, the other one died. Amazon's published warranty is 3 years and WD stopped honoring the warranty after one and a half years. This is the only forum with Amazon or WD where I can post a complaint to get support, I hope. I would improve my rating if this problem was solved.
Example Output:
negative
