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: Bought this in February 2018 and it's June 2018 now, stopped working overnight. Unfortunately for me I am in Europe now and don't know if I'll be able to get it replaced. Worked great when it was working and now it doesn't charge and when I plug in the cable to charge my phone through the case, it says a ridiculous amount of time until fully charged.
Example Output: negative

Example Input: I thought there was no hope left for my wool rug after my dog soiled it badly. My friend recommended stomp pads and they are amazing! I would have thrown out a $1200 rug if I hadn't found out about stomp pads.
Example Output: positive

Example Input: Once assembled it is very difficult to separate the top from the bottom. I broke the little clip separating it. It's made so poorly that even with the clip broke it's still hard to separate. My old fob slides together smoothly and this one doesn't.
Example Output:
negative
