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: Just used this on a 700 mile trip everything was going good. If I saved a clip I could pull it up on memory no problem. Night time came and noticed it didn't switch to night mode on its own you have to manually do it in the settings, no big deal. Problem is there's a finger smudge on the inside of my lens that only shows up at night. Then I get home plug the camera in to my laptop and no files? Take the sd card out and put in to my card reader and nothing. I will get a replacement and update my review..
Example Output: negative

Example Input: This was a steal! For 13.00 one would never know it is a pre owned case. It saved my phone more than once when it slid out of my lap while I was getting out of my suburban. The only thing I would change is making a belt clip for it to be worn on your person. Other than that AWESOME!!!! I'm a happy girl.
Example Output: positive

Example Input: It doesn’t work. Don’t buy from this seller. I can’t return it. It was a gift to my husbamd who is always out of town. By the time he got to it, it was passed the return date and I cannot contact Amazon about this item since they’ve changed the layout. It was an expensive mistake. Don’t buy.
Example Output:
negative
