Example Input: Best betta food on the market! Just make sure you soak the pellets for at least five minutes in tank water before feeding your fish. You would be surprised at how large they get.
Example Output: 5

Example Input: This shirt is cute but not worth $18.99. The pattern is just printed on, as opposed to being woven, so the inside of the shirt has that white/washed-out look to it, and doesn't match the outside of the shirt. It's also a bit itchy. I may have paid $5 for this shirt if I saw it on a shelf but I certainly wouldn't have paid $18.99. I'll probably send it back, honestly.
Example Output: 2

Example Input: Terrible screen protector. Firstly it does not fix to the screen properly on the edges and then the screen is not responsive in the middle. Will not recommend this product.
