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 bought this for my daughter and we were so excited about it. It worked for maybe 20 minutes tops... I thought that maybe my batteries were bad.. nope. We tried several different batteries and it still doesn't work. It's a cute puzzle, I just wish it still sang the song!
Example Output: negative

Example Input: Worked 45 days and died. Asked for a replacement or a refund. Told it was outside of return period. I see no return period listed. Amazon is not able to do anything because of 3rd party SELLER item. I was ripped off. DO NOT BUY FROM BIG D DISCOUNT!!!!!!
Example Output: negative

Example Input: I bought this as an Xmas gift and it arrived after Xmas. The main issue was that they sent me a Star Wars shirt in a size L, didn't even order that size or that shirt. Not the kingdom hearts shirt that is seen on the image. Disappointed.
Example Output:
negative
