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 tea is ok but it's not nearly as potent as the original product that was available 5-10? Years ago.
Example Output: 3

Example Input: I've had Amy and Brians coconut water - yum!, Vico's plain in the tetra pack - great! (the ones in the plastic bottle and some in the larger tetra packs are from concentrate - blah and yuck- don't get those!) , and the ones in the glass bottles- green cover- can't remember the name, but pure coconut water -great too.  This, one with pineapple- no good.  The added cane juice is superfluous to the natural sweetness of coconut water and pineapple juice.  It makes the water taste 'thicker' and not so healthy.  I wish these brands can just stick to the name of the drinks in their ingredients! (i.e. coconut water and pineapple juice! - no more!)
Example Output:
