Example Output: positive

Example Input: Received this “Auto Vox Digital Wireless Backup Camera” in a timely manner, installation was very easy. Took me approximately 1 hour from start to finish to complete the job. However when I first tried it, it worked but there was at least maybe a 5 second delay and I thought I could live with that. The picture was very clear with no interference, and that’s where it ends. When i got into my truck to head out, I put it in reverse and nothing! I spent several hours trying to relocate the transmitter and hardwire the wires to my backup lights. But nothing worked.
Example Output: negative

Example Input: Great starter book for those interested in trying out the Keto. So we all heard the craze about this new diet, however, the information I found was pretty intimidating. This book was really good at explaining what Keto actually is. The recipes are super simple and you probably already have the ingredients in your pantry. Definitely recommended for newbies looking into the Keto diet.
Example Output:
positive
