Example Input: Halloween is over but, I sent a bag to my daughters class for her share. The chocolate was fresh and enjoyed by many.
Example Output: 5

Example Input: I'd been hearing about the product for a couple of years and finally ordered some, but inadvertantly ordered lite! Yuk! After much anticipation, waiting for it's arrival, and then finally opening up the (cheap plastic) jar and putting some on a piece of bread to try it with.... it tasted like wall spackle. Ok, I've never eaten wall spackle, but I'm pretty sure it tastes like "lite" baconnaise. Then I realized after careful examination of the label that I ordered the "lite." Dammit.  Determined to finally taste the ORIGINAL baconnaise, I went back on amazon and (very carefully) ordered the ORIGINAL baconnaise. And it's pretty dang good! I'll leave a review of the original, non-lite product there.
Example Output: 1

Example Input: I love all different types of beef jerky, but not this one.  It has the flavor of grocery store bought beef jerky once you get over the overwhelming taste of salt. These sticks are cut thin making them tender and easy to chew, but they're just way too salty and definitely not worth $20
