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: If you already have the DeWalt batteries his is a great addition. This fan is so convenient to use that I end up using it all the time. It moves an impressive amount of air while at the same time is quiet. A 6Ah battery runs for over 10 hours on high.
Example Output: positive

Example Input: After just a few months of night time charging, the Apple watch won’t charge. Maybe if the seller sends me a new one for free I’ll write a better review.
Example Output: negative

Example Input: This was the first invicta watch I bought . I watched a bunched of videos on YouTube on watch reviews prior to purchasing and saw a video that showed that invicta is a bang for the buck . After receiving the watch I must say it does feel like a pretty solid watch especially for the price range . The watch I got did not have any Issues or defects .
Example Output:
positive
