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: These earbuds are just ok. They do NOT work 70 Deet away like it said. It’s always disconnecting and reconnecting so it interrupts any song or show you are watching. I would spend more to get a better product because this isn’t a good product.
Example Output: negative

Example Input: Another fabulous addition to the Brady saga! Sat down and read it cover to cover, didn't want to put it down. Sheriff Brady is on maternity leave and must stay in the background, depending on her deputies to find a serial killer.
Example Output: positive

Example Input: Nice, but became loose and unusable as a kick stand after only a week. Using another one now, we will see how long it takes before it breaks. Disappointed.
Example Output:
negative
