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: This is a close second to my all-time favorite, Jack Links Beef Steakhouse Steaks, which is the filet mignon of beef jerky. They're very similar in taste and price, but the Steakhouse edges out this one oh so slightly. Still pretty awesome jerky, very tender, and not a hint of fat or gristle. Bon appetit!
Example Output: 5

Example Input: This product taste like an orange juice, an artificial one but with less sugar and less flavor I didn't like it.
