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: This supplement reduced the days of my colds! This has helped me so much and I couldn't live without it anymore. This is one of the best things I bought so far. I will be buying this again
Example Output: positive

Example Input: I didn't have a bottom rail on my rifle so I needed to go get a bipod mount. After that it was easy. Would be nice if it had the option to get a rail mount piece or a bipod mount piece through the order. But I love them, they are strong and easy to put on and use.
Example Output: positive

Example Input: Once again Grace has managed to wrap me around another set of characters that keep me coming back for more and waiting with baited breathe! While this was NOT what I was expecting in the Virgin series, it stayed true to the Interstellar Brides series giving me characters that pulled me in and left me riveted from page to page. When I came to the end I am embarrassed to say that I shouts "NOOOOOOOO" for all to hear on the plane where I was reading.
Example Output:
positive
