Instructions: 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.
Input: I've tried a lot of different K-Cups and this is the weakest K-Cup coffee I've ever tried. It should not be labeled "Medium Roast", it should be labeled "Warm Water Tasteless" Roast. Too bad I bought a large box. What a waste...
Output:
Negative
