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: Unfortunately they didn’t work for me at all for they doesn’t work with soft tissue. My skin tissue is too soft and it won’t stay in place. So be careful unfortunately it won’t work for everyone. The firmer your skin is the better it may work.
Example Output: negative

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: Ruined my printer the yellow spread through to all my other colors. I hope this eventually cleans out of my printer. It worked ok for my paper prints at first but after 2/3 weeks it started smearing black and now yellow. It’s definitely not for printing on labels.
Example Output:
negative
