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 LED lights did not stick to my walls. I set them up in my room (efficiently, I made sure they shouldnt fall off) and left for a couple hours. When I came back they had completely fallen off. I messaged them to see if I could get my money back or if another one could be sent to me because I thought maybe the one I received was defective and they never even responded and its been 2 weeks.
Example Output: negative

Example Input: Normally these are the best corn husk but this last batch I received was not acceptable. Corn husk were so small I can't use them. No return. Wasted money. Disappointed
Example Output: negative

Example Input: After only using this lock a couple of times, the key will only turn part way, so the lock can't be unlocked. It took me about 10 minutes before it turned the first time, and now it's doing it again. If I can't trust a lock to open, I can't use it. This is worse than useless, since your lock could very well strand you.
Example Output:
negative
