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 first couple of bags were great. Really fresh, smooth, great taste. I thought I'd found the perfect coffee bean!! The next 5 bags .. stale. I canceled my order and went back to buying whole bean coffee from the supermarket. You pay a little bit more, but I've found that most of the time, the supermarket coffee is fresher. I prefer the taste of Weaver's but too many stale bags.
Example Output: Negative

Example Input: I was never much of a hot sauce fan until I tasted Black Market Hot Sauce. I was listning to the radio one morning and the creater/owner was giving an interview, It sounded interesting. The D.J.'s were sampling the sauce and raving about it, So I picked up a bottle at the local grocery, It's so good ! I keep a bottle in the kitchen and an extra bottle on hand for gifts and for taking to potlucks,barbecues and party's. Happy to see I can buy it online at Amazon.
Example Output: Positive

Example Input: This was a very disappointing coffee.  It is very weak, I had to set my brew to a medium just to get any flavor from it and  large is very watered down. I would find something different before buying this again.
Example Output:
Negative
