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: 4.5 stars The vented bottles helped so much with my baby’s gas problems. Took half star off cuz they are diff prices depending on color, wished they were same prices
Example Output: positive

Example Input: Love the locks! Very easy to setup and 100% serve their purpose. I have a very curious 10 month old little girl who is starting to get into anything and everything which was why I purchased this item. Very pleased at how well they prevent her from getting into things she shouldn’t be getting into.
Example Output: positive

Example Input: This was my child's favorite toy she got for Christmas... for 3 weeks. Then it broke in half. She is 3.5 and a confident walker, so this is not an issue of undue pressure on the cart. The legs snapped in half. Same spot and issue as almost every other complaint. It is not worth the money saved when it is only used for 3 weeks. Either don't get a shopping cart or splurge on a better quality one. Just don't waste your money on this one!
Example Output:
negative
