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: I bought these to use around the house instead of carpet slippers as they were making my feet sweat, and after being in work boots all day a bit of fresh air would not go a miss.
Example Output: positive

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

I purchased a second watch a month later and it came with something to keep the watch from being turned on accidentally. Indicating to me that my watch have been running for an indeterminate time.
Example Output:
negative
