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: Our family has liked every other flavored we have tried (BBQ is the best). We like sweet potatoes so we assumed would like these pop chips.  I was wrong, no one in the family likes the sweet potato pops chips.  I highly recommend you go to a store that sells the sweet potato before deciding on purchasing a large quantity.
Example Output: Negative

Example Input: Love these kcups. Box said "80" but contained only 35. Please send me the missing 45 kcups Newmans Own Special.
Example Output: Negative

Example Input: PopChips are delicious and much healthier than your regular potato chips. I love all the flavors !! It's also nice to get a variety box with single serving bags.
Example Output:
Positive
