Example Input: My honey has a serious sweet tooth, which I accommodate by preparing him a weekly dessert. Martha White's Muffin Mix is very convenient to prepare because it only requires one-half cup of milk, which I toss into my cuisinart; and wah-la six beautiful muffins with virtually no prep time. They are moist, delicious, and economic.
Example Output: 5

Example Input: I ordered these because I had purchased a bag of Sweet maui Onion chips from the supermarket. They were so good that I had to get another. The order came and I popped open a bag. They are very crunchy, so if you're into that, these are the chips for you. However, they do tend to get really salty. I found myself having quite a few sips of beer when eating these
Example Output: 3

Example Input: My son really enjoys Earth's Best lentil! He eats the entire jar for dinner and always wants more. The product shipped very quickly.
