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: The set is beautiful and sturdy. Very comfortable seating and the blue color is pretty. There is a lot of nuts and screws involved in the assembly. We used a power tool to assemble. We had no trouble putting the pieces together. It took us two hours to get it altogether, when done it will have been all worth it.
Example Output: positive

Example Input: This is a very easy-to-use timer, the big numbers are great and I can hear it go off quite a distance away! I use it a lot when I'm using my PC because time just seems to disappear when I'm back in the office working on it! The magnetic back is nice so that I can put it on my fridge.
Example Output: positive

Example Input: The copper finish came off the steel base. Food sticks to those blemishes. I have other similar products that have performed well. I definitely do not recommend this product.
Example Output:
negative
