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: Worn once by my child & washed once my me. How is it possible that it has a large hole in it already!?!?! The amount of piling after just 1 wear & wash is ridiculous too! The fit is great & they seem warm, but if they are basically disposable socks, what good are they? Wish I could get a refund. Would not recommend.
Example Output: negative

Example Input: Bought 4 of these in different colors worst buy I ever made they are very poorly made and rip after one day of packing it please save your self some time and money and dont order
Example Output: negative

Example Input: I got this & it did not work, so I put brand spanking new batteries in it. It still didn't work. I tried the batteries in another item & it worked fine. So it wasn't the batteries, it was the product. Do NOT buy this!
Example Output:
negative
