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 thought surely the other reviews saying the product cut their baby were an exception. But bo, this product is defective and cut my baby and caused him to bleed. They shouldn't be allowed to sell these. Save yourself and your baby and just buy the windi.
Example Output: negative

Example Input: Wow! And not in a good way. I had color treated hair and was looking for a slight tint to cover my grey....well 3-5 minutes later I'm left with bright red hair ONLY in the places that were dyed blonde. Don't not cover any other places. AND stripped all my other color away.
Example Output: negative

Example Input: Amazon is great with their refund policy. I never could get this bell button to pair with my chime even though they are from the same company and the description assured me it would work with any Zenith chime set. Wrong. Thank goodness for Amazon and their amazing customer service. Many thanks. For now, anyone wanting entry will just have to use the 5 knuckle method and knock!
Example Output:
negative
