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: Ordered size small in blue. I'm about 5'8, 150 lbs with more of an athletic build. This dress fits perfectly. The color is more vibrant than I thought it would be but I love it. Fabric is pretty good quality and there is a little stretch in it, but very comfortable. Very happy with this purchase.
Example Output: positive

Example Input: I got these headphones for two reasons: 1. I wanted something to put in when I ride on my indoor cycle trainer in the winter and watch movies. 2. I was sick of my headphone cable getting caught on stuff at the gym. These headphones have exceeded my expectations. They sound surprisingly good and connect easily to my iPhone. I haven’t had any issues with connection dropping and the battery lasted a lot longer than I thought it would. Please note that I am rating these based on what they are, and not on what they are not. These are not audiophile headphones. They don’t sound mind-blowingly good. In my opinion, they sound better than the EarPods that come with my phone. Not way better, but better.
Example Output: positive

Example Input: Do not buy these they will get stuck to your tire and you would have to go to tire shop for new air tube! With pliers, vice grips and oil penetrate they would still not come off!
Example Output:
negative
