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.

Ex Input:
I was excited to see that Amazon is selling 100% Kopi Luwak. However, these beans were a huge disappointment because they had no aroma and flavor at all. I'm guessing that they sent stale beans because there was no roast date printed on the bag.

Ex Output:
Negative


Ex Input:
Amazing concept... not fried, not even baked... Popped like Popcorn... !!!! This is another product for my Weight Watchers regima. Each bag is only 2 points.. I love this snack for mid morning in between breakfast and lunch. They taste really good.. my favorite are the Bar-b-que, Salt & Vinegar, and the Sour Cream.. they are all good though.

Ex Output:
Positive


Ex Input:
Warning: it contains food preservatives. Other than that it is fine, but presence of preservatives in dates (!) justifies my low 2 star rating.

Ex Output:

Negative
