Given the task definition, example input & output, solve the new input case.
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: These are junk! Both bulbs have burned out within a two month period!! I cannot believe that this company can be in business with such poor quality. I have used infrared lights for my ball python for many years now and I get a varied range of months from a bulb, but I have never gone through two bulbs in a matter of two months! I am very disappointed.
Output: negative
The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, it's a negative review.

New input case for you: Originally got these for girlfriend who sometimes snores and wakes me up in the middle of the night. I decided to try one out myself and it enabled me to breathe so much better. I couldn't believe how much more airflow i could get while inhaling with this device in my nose. It was if something was blowing air into my nose. I actually slept a whole lot better going to sleep with one of these. It was first time in a long time I slept a solid 9 hours without waking up one time. I will forsure be using these for myself now.
Output:
positive
