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: The item was delivered in good condition but when used on two different USB ports on my Samsung flat screen tv to power a fire stick device ,a message was displayed saying not enough power for this device.
Example Output: negative

Example Input: I absolutely love these! I've never installed something like this before. It took me a little longer than it prob would have taken most men, because I didn't think the directions were quite clear so I had to do some thinking on it but I'm proud of myself.
Example Output: positive

Example Input: Terrible, but I should have known since it was so inexpensive. Came vacuum packed, and was completely misshapen when unpackaged. Also, the advertisement said that it was a two-pack, only one pillow came.
Example Output:
negative
