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 easy to use yes. But it didn’t hardly give any color. The color I had was very spotty! It took using over half of the bottle to even start to notice anything.
Example Output: negative

Example Input: I got this product for my one year old for her birthday and this buggy is not worth what i paid for it. It is very flimsy and constantly falls apart while she’s pushing it
Example Output: negative

Example Input: I am a school teacher and I go through tons of pencils in my classroom every year. The lead was not in the center so when you sharpen them the wood comes all the way out on one side so unless you whittle them with a knife they are worthless.
Example Output:
negative
