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: Whatever you do, please stay clear of this product. Amazon should stop selling it immediately. I have now made three separate purchases of the same product hoping to find six trims that did not arrive all scratched up. After three attempts, the product receives a major fail. Not one trim arrived in new shape. And the last box arrived with three trim missing. The product is junk from China and every piece just sits on top of one another and easily scratches the surface. It's too bad because the product itself seems well made. Somebody needs to improve quality control.
Example Output: negative
