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: The camera quality is horrible. There is no way it is 24 megapixels as I just had a 20 mp camera and it was much better quality. Also, within 1 hour of using it it started freezing. I returned it. I feel like the 5 star reviews are fake as I know companies do that. I cannot imagine anyone being happy with this camera.
Example Output: negative

Example Input: Just received these in the mail today. They are really soft and comfortable. I ordered a M. I'm 5' and approximately 120 pounds. It's a little loose but they are comfortable for sleeping. In my opinion the material quality is very good. Not thin at all.
Example Output: positive

Example Input: I have these on all three queen size mattresses in my home. They work great for protecting the mattress from moisture and I do feel like it helps considerably with the heat of laying on a memory foam pad. One reviewer left a photo of the mattress pad destroyed by washing. I had that happen once recently. I thought that somehow they had changed the product, and they were no longer washable and dryable. However, I later came to find out that the cold water was being plugged in my washing machine by dirt in the hose filter, so the water in my washing machine was primarily hot and thus it melted the mattress protector. After correcting that issue, I was able to wash one of my other mattress protectors on warm and dry in the dryer on medium heat with no issues. I added a couple of dry bath towels to the dryer when I dried it and it really helped it dry quickly and easily, since it doesn't wring out well in the washer due to the waterproof nature of it.
Example Output:
positive
