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: Very easy company to deal with. I own a cleaning business and my employees love these mops. They pick up great and can reach under just about everything. A little pricey but worth it!
Example Output: positive

Example Input: I bought these on August 22nd and installed them right away. It's been a little over a month and around 5,000 miles and they are completely warped. Very disappointed with the overall quality of this product.
Example Output: negative

Example Input: I make this pizza every Friday. It's easy, healthy and taste great. You can also make just bread where you cook it 11 minutes on 450 degrees. Put it in the toaster, put some butter and cheese on it. Perfect Paleo food.
Example Output:
positive
