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: 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

Example Input: ....like just about every other page!! I couldn't believe when I started reading this (with Book 1) and around the fifth chapter, things started feeling freaky. Dialog didn't continue, descriptions faltered, and why? Because every other page was missing. When I checked the other books in the bundle, the same thing occurred. Unfortunately, there's no way that I can find to complain about this to anyone at Amazon. I tried re-downloading, but as I 'm in the midst of another bundle (and this is the first time this has happened since I bought the kindle) I haven't checked to see what's what yet. I will edit this review with an update when I have done so.
Example Output: negative

Example Input: "It's such a quick and easy step every morning to clean my face and get me started for the day. It makes my skin feel so clean and smooth and has really helped clear my acne."
Example Output:
positive
