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: This item does not heat despite being turned on. In addition, the rack was nearly impossible to put together to be free standing. The provided screws were too big for the holes. Terrible product! To top it off it had absolutely no instruction on how to put together as freestanding.
Example Output: negative

Example Input: I was immediately disappointed with the quality of this ring. It bent as I was removing the tag. It’s pretty and it hasn’t turned my finger green YET, but overall disappointing.
Example Output: negative

Example Output:
negative
