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: The slots are a bit small for my liking but this case is amazing and my 3 and 7 year old fight over who gets to use it. Guess I'll have to get another one.
Example Output: positive

Example Input: It's exactly what I needed, easy to cut and put in my shoes. Such as running shoes, but it needs more space after put the deep heel insert. Overall, it's good.
Example Output: positive

Example Input: I actually purchased this wig because the price was right and I wanted to see what I looked like with ombre hair. It is comfortable and came with a bonus wig cap to flatten out my natural hair. I love the look! My neighbor asked to borrow it for Halloween (she has super short grey hair). She tried it on and looked 10 years younger. It's definitely a fun piece to own.
Example Output:
positive
