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 reported a case i bought from amazon missing when it was not delivered to me when amazon said it was. the person i talked to online said that everything was fine and they would send me a new one and not charge me for the first. A month later amazon still charged me again for the phone case i finally received from them. Double price rip off from amazon service department.
Example Output: negative

Example Input: I received this chair today and definitely regret buying it. The off gasses made me and my son both sick with difficulty breathing and sore throats. There was no odor however some chemicals do not have a smell. There is formaldehyde per the package insert. Wish I had known this before buying. The reviews seemed to convince me that it was also pretty comfy but sadly I would not want to sit in this chair for More than a few minutes. It's very firm and not the chair I was hoping for. It's currently outside off gassing and will most likely keep it because I'm too lazy to pack it back up. It will probably grace the corner in spare room to torment any guests we have in the future.
Example Output: negative

Example Input: The advertising never mentions that it is only compatible with Windows. Chat with support confirms that fact. So, I had to go through all this grief because of Autel!! If you have a windows system (must be the only system in the world) you might be OK.
Example Output:
negative
