Example Input: I'm a big Juan Valdez colombian fan. This Jamaican stuff doesn't have the kick that I love from coffee. It's sorta flat. Especially for something I spent $75 for two lbs. Goin Back To Colombian (twang twang)
Example Output: 3

Example Input: Wrigleys' 5 FLARE sugarless gum is Wrigleys' sugarless replacement for their "Big Red" cinnamon gum. 5 flare seems to be difficult to find in stores. Thanks to Amazon I always have a supply. 5 FLARE is also the longest lasting gum I have ever experienced both in flavor and durability. It is positively the best cinnamon flavor currently on the market.
Example Output: 5

Example Input: I didn't care for Kiwi Berry Switch. It was very sweet and not refreshing at all. Also, at 135 calories in an 8.3 ounce can, it actually contains a lot more calories than regular soda. I know it is all natural and doesn't have HFC (High Fructose Corn Syrup), and I appreciate that, but it also doesn't have much actual kiwi or berry juices. The drink is VERY sweet, but sweeter than 100% fruit juice, sweeter even than your average can of soda. I can't say I would ever buy this product or recommend it to anyone else. There are better natural sodas on the market, as well as better 100% natural juices.
