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 bought this set but it’s missing the kneaded eraser that was mentioned in the title, description, and pictured. This was primarily the reason I bought this item and I’m pretty pissed actually
Example Output: negative

Example Input: Great book if you bought an air fryer and want some more recipes!I just tried a few recipes, but it's really a good starter book for learning the initial use of your fryer.
Example Output: positive

Example Input: I read a lot of good reviews on Calphalon pans, so I wanted to give it a try. I thought maybe getting a little expensive pan (it was $39 when i got it) means that it will last longer, but it didn't. I was hoping for a pan that would last at least 3 years, but this lasted less than 8 months. I am very disappointed. I don't really recommend it. For a pan that will last less than a year, get something cheaper.
Example Output:
negative
