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: If you like strong coffee, as I do this coffee is over rated. I found it weak, with a sickening after  taste.
Example Output: Negative

Example Input: This tea is very good.  I discovered it while visiting in California. The moment I got home I searched local stores for it and I was not able to find it.  Finally I decided to see if Amazon had it and they did and I bought two boxes.  As long as they make it I will buy it.
Example Output: Positive

Example Input: I got this food for my dog that is allergic to corn, wheat, potatoes, flax, fish, and pork.  I had the hardest time finding a food that he wasn't allergic to.  I'm so glad I found this food.  He is finally eating and starting to put on some weight.  It is a little pricey but I think it is worth it for such a good product.
Example Output:
Positive
