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: This product arrived with a bent pole and two missing rollers and not instructions to assemble. I promptly returned the item and went to a local store to purchase.
Example Output: negative

Example Input: The brushes have good quality. They are soft, strong and easy to clean. It is good to have a lot of different brushes. As a beginner, I’m very happy with my purchase (I know they are all useful, I just need to learn how to use them all).
Example Output: positive

Example Input: Same light quality and brightness as our 100W halogens, which last little more than a year. Good build quality on these lamps, fit in our sconce lamp sockets as expected. Highly recommended.
Example Output:
positive
