Input: Consider Input: With the Prime shipping, this made a great last minute gift. It seems a little pricey for the amount of fish, but the quality was good (according to the person I gave it to). In the end, I think this is better than a fruit basket or something similar.

Output: 3


Input: Consider Input: For those who love salt and vinegar potato chips, this is the one to choose. The flavor is zippy and tart, with no unpleasant chemical aftertaste like the less "natural" versions of this snack. The 2-ounce bags are just right to share at lunch. The chips are a little greasy, and that's why I've given them 4 stars instead of 5.

Output: 4


Input: Consider Input: I like to brew a k-cup cocoa into my coffee for a nice mocha.  This dark chocolate flavor is quite nice, especially mixed with Double Black Diamond coffee.  Though not the very best, it is good, and the price is right, compared to other brands.


Output: 4
