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 am a senior and don't get the exercise I know I need. This has helped me so much with the circulation in my legs and given me muscle that I haven't had in years. I love it because I can sit in front of the tv or while on my computer. I usually use about 30 min every time and I love it.
Example Output: positive

Example Input: These pants are awesome. They protect your legs very well for welding. If you use your knees for low level welding, brick work, tiling, carpets or roofing, your knees will wear out before these pants do.
Example Output: positive

Example Input: Recently bought three sets of these laces in different colors. Have replaced all of the tie laces in my sneakers with these and am very happy. They were easy to use and have eliminated that feeling of your shoes tightening as your feet swell throughout the day. Plus they make putting your shoes on and off so much easier. Of course they frayed after cutting them, but that is no big deal as they ends are entrapped in the end closure. Good bargain that this price.
Example Output:
positive
