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: Buying these is like playing Russian roulette. If you get a good one, like a friend of mine's, they are well worth the price. But the one I received had parts that did not lock together and the rotor wobbled. I returned it.
Example Output: negative

Example Input: These earbuds are just ok. They do NOT work 70 Deet away like it said. It's always disconnecting and reconnecting so it interrupts any song or show you are watching. I would spend more to get a better product because this isn't a good product.
Example Output: negative

Example Input: DO NOT BUY THIS PRODUCT!!! first off, it didn't come with an adapter, second, you have to tape the wires to the cords which do not stay and make me very mad. If I could do negative stars I would and I want a refund!!
Example Output:
negative
