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: 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.
Output:
negative
