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: Love ur products but this one is NOT good. This photo is 8 hours after class. I’ve had this mat about a month and the stains never completely disappear. I’m a woman and I do sweat but it’s embarrassing to see the outline of my body at the end of class...to the point where people start staring at my mat and at me. Yuck. Please let me return for refund if possible.
Example Output: negative

Example Input: The product did not come as pictured! I bought this specifically because there were no fire & ice condoms however the package I received had fire &ice condoms rather than the charged condoms!
Example Output: negative

Example Input: Don’t waste your money on these. Extremely thin and cheaply made. Arrived already cracked and damaged. You are better off to spend a little more for a better quality product.
Example Output:
negative
