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: I wish I bought these sooner. I noticed a significant savings in just a month as I used to leave to lights burning 24/7 in the front and back yards. These LED lights are very bright in a positive way and help me to easily see my front driveway area as well as my back patio area in the back.
Example Output: positive

Example Input: This is a piece of crap have only had a week and there's no more motion I don't write reviews but this is straight garbage I will be returning this. Don't waste your money on this one. I would give it no stars if I could. Very disappointed
Example Output: negative

Example Input: Bought this for my wife's birthday. She said she wanted a simple Gold cross that would not rust. She's worn it 24/7 since I gave it to her back in October and it is still as shiny as the day I gave it to her. It does not rust, change colors, or cause any rashes for her.
Example Output:
positive
