Input: Consider Input: The last bag of these I got from Amazon had a lot of hollow bisquits.  It was weird ......  they just weren't solid like they should be.  I'm going to switch to another brand of grain-free dog bisquits now as there's no sense in paying for something I'm not getting (and these are expensive!)  And if it wasn't for the good packaging I'd wonder if bugs had gotten to them..... but I don't think that's possible.

Output: 2


Input: Consider Input: Delivery of the product was quick, however the items are smaller than how they appear on line. Next time I would order the larger size.

Output: 3


Input: Consider Input: I bought these for my boyfriend who really likes honey roasted pecans in salads that I have at a couple of restaurants. Plus, he likes nuts, pecans, almonds peanuts. He loved these. I actually ordered 3 cans instead of the gift tin, so he could take one to work, or his place, and stay fresh longer. Although I don't think freshness will be an issue, they won't last long......lol


Output: 4
