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: Order came on time, but the threads on the shower outlet were bad. Had to get a master plumber to fix a less than 10.00 dollar item. A lot of work was done to the bathtub to get to the tub spout. The shower head could not be used nor the tub spout to fill the tub. I expect a full return from Amazon.
Example Output: negative

Example Input: Peice of crap dont work cant pick up nothing here so when I called company to send it back the company refused to reimburse me so thank God I had Amazon insurance
Example Output: negative

Example Input: I absolutely love my Pixie Cup! I've used it for three cycles now and can honestly say I wish I'd switched years ago. I was really nervous about the inserting and removing process, but it is really easy. I used to be strictly pads, but this has completely changed that!
Example Output:
positive
