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: Product damaged enroute! Refund sent? Only problem is now I must wait over a week for the money to be returned to my account so I can reorder it! Great customer service Amazon!!!
Example Output: negative

Example Input: Day #1 and one tire broke! I would at least like to know if there is a possibility of ordering spare ones. All the rest is fine, but really I can't understand that it's sold as heavy duty and it breaks on the first ride, just carrying beach stuff
Example Output: negative

Example Input: It doesn't actually absorb liquids, it is permeable and they still stain the floor. Now this matt is ugly and deformed and merely covers the oil stains it has allowed to hit the floor.
Example Output:
negative
