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 thought the impeller was broken so I purchased a new one and unfortunately learned that it is the filter itself that is no longer able to pump water. I bought this a month ago. My turtles are not happy.
Example Output: negative

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: Wow! I should have ordered one of these A LONG time ago! This is so handy! I bought it to make rope fondant by twisting two cords around each other and it is SO MUCH EASIER than rolling my own fondant and being consistent. I'm excited to try the other shapes and figure out a way to use them. It's not a fast process - because it takes time to twist the bar around to push the fondant out, but it creates a great product for your time. Also--easy to clean as it pushed the fondant out it self. I highly recommend this.
Example Output:
positive
