In this task, 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: My son thought he was getting specific characters with an in-app purchase (he used $12 of his own birthday money). However, the characters it showed were ones that you MIGHT get. Guess it is random what you get. Needless to say, I had a very disappointed 10 year old. Hate the deception. Don't waste your money.
Example Output: negative

Example Input: I have fed my dogs Instinct Raw Boost for years. I have two big dogs, one with digestive issues, and then added a third big dog to my pack, so that brand of food was too expensive when I have to buy a 21lb bag every week or so. Dog Food Advisor gave this 5 stars, so I tried it. My problem dog didn't have any problems at all transitioning to this food, and my Great Pyrenees with allergies has had no issues. I am extremely pleased with this food. I would highly recommend it.
Example Output: positive

Example Input: I have normally always purchased my Bates at a local boot store.i sought out the same exact brand I have always gotten and the fit is totally off. My feet hurt at the end of my shift. I will not order these online again.
Example Output:
negative
