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: For hours I have tried to figure out this machine. It finally got the best of me. It is being returned. I can't figure out how to bind 8 1/2 x 11 size paper. It leaves a half punched hole either at the top or the bottom of the paper and the combs they give you are too long for this size paper as well.
Example Output: negative

Example Input: Didn't Like the smell at all. I put it on my face but it was way too greasy. I heard that it was good for scars from acne but I wouldn't recommend if you have oily skin... It really had a fishy scent to it
Example Output: negative

Example Input: These were counterfeit. I had previously ordered the Kitchables espresso cups. Those came in distinct packaging and had their logo stamped on the bottom of each cup. This order of 8 oz coffee cups were not made by Kitchables although they were marketed as such. They had a different stamp on the bottom of each cup, and they came in nondescript packaging. Also, there were scratches and bubbles in the glasses.
Example Output:
negative
