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 ordered from Amazon because the only 5oz cups locally seem to be child oriented and not for an adult bathroom. Ha! My dixie cups have riddles on them and are as cartoonish as the ones I could have bought down the street. I'm throwing them out and getting a hard plastic cup. So mean to send something other than was pictured!!!
Example Output: negative

Example Input: Shipped out on time and arrived early! Very neat package and perfect invoice/product. Product package was sealed and when opened, product was fresh. Good Quality product!!
Example Output: positive

Example Input: The book was extremely helpful in revealing common mistakes writers make about such things as "point of view", "beats", "flow", and other writing topics that have a tendency to keep a manuscript from being readable. i refer to it quite often and bought a copy for a middle school language arts teacher that I know.
Example Output:
positive
