Example Input: I thought I was doing my kid a favor when I invested in a case of Earth's Best dinners.  Unfortunately, the second ingredient (after water) for all of these is....applesauce.  Or in the case of the "Sweet Potato & Chicken" variety, it's sweet potatoes, followed by apricot puree.  After getting used to the sweetness of these (try 'em - they're like jam), it's difficult for kids to adjust to "real" food.  From now on, I'm going to stick with just pureeing home-cooked food.  It's a lot cheaper, too.
Example Output: 3

Example Input: This variety pack is perfect for when you want something crunchy and salty. The selection of flavors were great choices for me - I liked them all. The portion keeps you from overeating, and they are healthier for you than potato chips, even the baked ones. I recommend these and will be buying them again and again.
Example Output: 5

Example Input: What's to say - Pop Chips are great!!!  Kudos to the PoP Chip makers.
