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: It typically works for a few turns and then nothing comes out after that. I would shake it to try to get peppercorns to feed but that never really helped much. Only emptying it, clearing the neck and reloading it would get it working again for a few more turns. Seems like the neck is too narrow and gets clogged inside. I finally tossed it out because even the disposable McCormick pepper grinder works consistently without all the fuss.
Example Output: negative

Example Input: I’m so excited! These actually worked I was surprised! I’ve got three kids who love to spill their drinks at the restaurants!! Momma was prepared today! It is on the cups they give u at restaurants in picture.
Example Output: positive

Example Input: This young woman knows what's important and how to say it. There is a brokenness and tenderness in these pages that gave me great encouragement. You might want to get more than one copy so you have one to keep and one to give away.
Example Output:
positive
