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: I bought this for my daughter and we were so excited about it. It worked for maybe 20 minutes tops... I thought that maybe my batteries were bad.. nope. We tried several different batteries and it still doesn't work. It's a cute puzzle, I just wish it still sang the song!
Example Output: negative

Example Input: It is deceiving in that it did not come with the portable charger and cord as it advertises. We were thoroughly disappointed when the package came and that was missing. The whole point of my 10 year old son wanting the backpack was for that reason. That being said, if you like the backpack the. You will be happy. My son has been in school for 2 months and no damages from the backpack can be sighted.
Example Output: negative

Example Input: Wasn't expecting to like it that much, but I'm genuinely surprised at how satisfied I am. There's a small mirror inside, which is handy, two pockets for cards, and a slot where you can put in bank notes, cash, receipts, memos, etc. I never had a screen protector, and now I probably never will because of how the case naturally keeps it covered when closed. I also appreciate the fact that I can set it on the side and the case will help it stand hands-free.
Example Output:
positive
