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: Get the Otium Bluetooth headphones. I mistakenly bought these thinking they were the same because they look identical but they were not the same. Bluetooth connection would break up periodically. Sound was average and they broke in half when I pulled them out of my gym bag. Poor overall quality.
Example Output: negative

Example Input: These gloves fit comfortably, give a nice grip on the golf club and look nice. They are easy to get on, while also fit snug. The material feels like very good material and isn't irritating.
Example Output: positive

Example Input: If you use hair products such as clay's then this is a must. I use it once every two weeks instead of the recommended once every week and it really does do a great job at cleaning out all the gunk that is left over that normal shampoo's do not remove. It a must have for any avid hair stylist to keep your hair from becoming to heavy and not getting the volume you're looking for.
Example Output:
positive
