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 have no regrets with this keyboard. I was definitely not looking for this keyboard originally. I was going to settle for a keyboard that looked like a typewriter. I didn’t know I was settling though. I didn’t know I wanted one with crazy lights on it. I am shook to my core. Everyone has asked where I got the keyboard from.
Example Output: positive

Example Input: Fast shipment and easy to install. I don’t have any mechanic experience and even have my friend install the back off camera for my car last year. My friend is out of town for his business trip and I have to install it by myself and I did it just in 30 minutes!!! It worth my dollars and quality is good over my expectation. I am still exploring all the features of this new car radio (sorry I am not a very high tech person) but so far it meets all my needs and functioned very well for me. Quick and easy to connect with my smartphone.
Example Output: positive

Example Input: Useless, basically its like a kazoo for your nose, does not alleviate snoring at all, if anything it made by nose feel sore the morning after, and is easily clogged if you have sinus issues.
Example Output:
negative
