Input: Consider Input: Having eaten (and re-eaten) my way though all of the DAS caramel range, this remains my all-time favorite, and the one that usually gets the most rave reviews when I share them (which isn't an easy thing to do - just try one and you'll see what I mean).  I've been a caramel fan for ages, and while Werthers Butterscotch will do in a pinch, nothing has come closer to what my mother used to make than these.  They are chewy, buttery, and the little crunches of salt are spectacular (OK my mother didn't put salt in hers, this is an improvement).

Output: 5


Input: Consider 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

Output: 3


Input: Consider Input: I LOVE spicy ramen, but for whatever reasons this thing burns my stomach badly and the burning sensation doesn't go away for like 3 hours! Not sure if that is healthy or not .... and you can buy this at Walmart for $0.28, way cheaper than Amazon.
