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: Well, I’ve given it 6 weeks, using faithfully morning and night. I was hoping for longer lashes (but I wouldn’t have given a one-star review if I had at least gotten fuller). I haven’t noticed any change. To top it off, the last 2 weeks I have been babying my tube, since it developed a crack/leak along the bottom edge.
Example Output: negative

Example Input: Kit is basically unusable. The negative lead has no continuity and seems to have a broken wire. The kit has a lot of useful items in it, clips and such, but is rendered useless with a broken lead.
Example Output: negative

Example Input: Holds a lot of pencils. The pockets are kind of small, and some pencils almost don't fit lengthwise. Can be frustrating if you have a long pencil that is sharp and has an eraser on it - have to be careful to not break the tip in the closing of the box.
Example Output:
positive
