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: Product damaged enroute! Refund sent? Only problem is now I must wait over a week for the money to be returned to my account so I can reorder it! Great customer service Amazon!!!
Example Output: negative

Example Input: These are very large mouthed straws. I thpught they were regular size, but they are more of a smoothie or larger type of straw. I'm not sure who needs a straw this large.
Example Output: negative

Example Input: Plastic button covers the on/off button. You have a hell of a time turning this on and off then at random (not even trying to turn on or off) the turn off screen pops up. I've ordered many Snugg cases but this one truly sucks. Where the pen holder is - is where the strap to hold it close is. If you put a pen in the holder the close flap keeps popping open.
Example Output:
negative
