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 bands work great and I like the different colors which make the Fitbit more versatile. I wear my Fitbit all the time so I am able to change the band to coordinate with what I am wearing. Great price and made very well. I have had mine for about 2 months now and have had no problems. Received the item in a timely manner!!
Example Output: positive

Example Input: Super cute! I love these for an easy everyday pair of earrings and to keep my piercings open. I have a baby so I need studs that aren’t easy to rip out. These are perfect.
Example Output:
positive
