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 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: 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: Had used another waterPROOF case for the last 3 years. Had to replace it twice. Decided to try the CellEver case. Fits great, easy to install and fells better in my hand. Bought one for my wife as well.
Example Output:
positive
