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: This would have been the easiest 5 star review... if I had actually recieved the blood orange flavor, but some genius decided that regular orange is close enough to blood orange and sent it to me. Ok... mistakes happen, no big deal right? Usually it isn't, but the vendor will not return emails or fix their mistake. Long story short don't buy from this vendor
Example Output: negative

Example Input: Love this so much! I put my tree up early, and realized it was broken:( so I ended up with this one because all the ones in stores were SO expensive! This one was super affordable! Easy to assemble and I currently have Halloween decorations all over it! I love it so much!!’
Example Output: positive

Example Input: Product came too large but seller was accommodating in sending me a smaller size for free. If you’re going to purchase, purchase one size down. Product does the job.
Example Output:
positive
