Definition: 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.
Input: This product is a piece of joke!! Not even worth a penny!! It's cheaply made and does not work its purpose like it says. Bought one and had to throw it out. Only giving one star each because it required it. Not happy at all that I wasted money on it.

negative
