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 item does not heat despite being turned on. In addition, the rack was nearly impossible to put together to be free standing. The provided screws were too big for the holes. Terrible product! To top it off it had absolutely no instruction on how to put together as freestanding.
Example Output: negative

Example Input: Well, I’ve given it 6 weeks, using faithfully morning and night. I was hoping for longer lashes (but I wouldn’t have given a one-star review if I had at least gotten fuller). I haven’t noticed any change. To top it off, the last 2 weeks I have been babying my tube, since it developed a crack/leak along the bottom edge.
Example Output: negative

Example Input: I love this Desk Pad. It is everything as described from the seller. The stitches are very well done and it is completely reversible. Both colors look nice and compliments my room and walls. The pad stays on my desk and my mouse glides smoothly. However, if you are someone who does not like a slippery pad for their mouse, this product might not be for you.
Example Output:
positive
