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: This was a steal! For 13.00 one would never know it is a pre owned case. It saved my phone more than once when it slid out of my lap while I was getting out of my suburban. The only thing I would change is making a belt clip for it to be worn on your person. Other than that AWESOME!!!! I'm a happy girl.
Example Output: positive

Example Input: Keep your money! I bought this so I could check my husbands BP. I took it out of the package, set it up, and took his BP. The sphygmomanometer broke in the first use. I didn’t even get to finish taking his BP. It felt really cheap too. I also didn’t like that I couldn’t hook the sphygmomanometer to the cuff. It is part of the pump.
Example Output: negative

Example Input: I like having a variety of fidgets for my students. This set has a nice variety for them to choose from. The quality of these products is good and makes me feel like they will last awhile. Not like some of the cheaper made things out there.
Example Output:
positive
