Example Input: I used these lollipops for a candy princess costume for my daughter. They came in perfect condition and exactly like the picture shows. They do come in a group of 16...such a great value! I was extremely satisfied!
Example Output: 5

Example Input: I admit that I fully expected to dislike this product, and approached it with a dismissive attitude - something that's this trendy can't be any good, right? well, I was wrong. The ONE coconut water is refreshing, delicious, and just barely sweet. Really wonderful stuff. The hint of pineapple adds a little bit of acidity that enhances the basic taste of the water. i bet this would make a great summer drink too, but I only had one so I didn't get tot try that. My problem now is that it's been out of stock, so I can't get more.
Example Output: 5

Example Input: These Sweetleaf "flavored" products are only for people who want something really sweet with just the very barest whiff of some flavor (you probably won't even be able to tell which one it is). If you're looking for a product that's about half sweetness and half flavor, THIS ISN'T IT. I urge you to save your money and look for another solution.
