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: 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: These are very handy! Each marker has the same color but one end is more of a thicker marker but as big as a regular marking pen. The other is a fine tip marker for doing more detailed work. Great for adult coloring books or anywhere you would need a fine point or a marker not as thick as the regular ones.
Example Output: positive

Example Input: had it less than a month dropped my phone from less than 4 foot (getting into my vehicle) the top of the case popped off allowing the upper left of the screen to crack. the power button has come off of the case so now you if you do not have a long fingernail you cant hit the button on the actual phone. So Now I Will Be Out A Cracked Screen on My Phone. If I Had it to do Over Again Definatly would Rethink this Purchase.
Example Output:
negative
