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: Really good construction, not the usually cheap plastic feel. I love the multiple colors on each truck. The return mechanism is really nice and fun. It's a must buy for every child!
Example Output: positive

Example Input: So far we really like it! We need to buy another since this one is short, but we are pleasantly surprised with how well this hose works. There's no complaint here on leaks. It does drip very slightly but our regular hose was much worse, a constant leak ( we have very hard water) so we think this is a great change!
Example Output: positive

Example Input: My wife loves it , it tracks her heart rate through out the day and it displays on the watch and app. You could choose up to three physical activities for the watch she has walk/run/workout. Be sure to select it before starting the activity because it won’t calculate the calories correctly. She worked out didn’t tap on the work out and only burned 60 calories but the second time after selecting work out it registered 510 calories. Everything works well except the sleeping majority of the time it’s doesn't register her sleep, probably only twice after having it for a month already Overall affordable accurate except for the sleep.
Example Output:
positive
