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: It was very easy to put on the wall as it came with the screws and dry wall anchors, and works well for my ukulele. The materials do feel a bit cheap, but it holds up well.
Example Output: positive

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 Input: Literally can not get the back out to put the picture in. It’s like the sides go underneath the frame and the back doesn’t lift out. I used a butter knife to try and get it out and it ripped up the backing but it still won’t come out.
Example Output:
negative
