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 toaster oven worked fine, but the different 'functions' were pretty much the same thing. The heating element stopped working after a year. Keep shopping.
Example Output: negative

Example Input: Really does a good job of pulling the dialogue out on the tv shows. Over all sound is great. Lots of available adjustments which I really like. I added a woofer and it works great with the sound bar. We are very happy with the purchase.
Example Output: positive

Example Input: The "portion" that goes inside the wallet ripped in less than a month. Will order from different company next time and will pay more in hopes of better product.
Example Output:
negative
