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: As a mother with two children, when the children have ear problems, I always get in a hurry and get used to using bulky flashlights to observe whether there are foreign bodies, and the kids will also appear a little resistant. I've never used any otoscope before, so it's a very fresh experience. The instructions make it easy to operate and show clear pictures on my iPhone. For families, this is a practical tool for parents with children.
Output:
positive
