Example Output: 5

Example Input: Switch tastes more like chemicals than juice. I was expecting something along the lines of Orangina, instead it's closer to orange soda but without the carbonation level that makes orange soda enjoyable. For a small drink (8.3 oz), it's pretty high in calories (140). Frankly, I don't think the flavor is good enough to justify the caloric level. Bottom line: If you're die-hard soda drinker, this might be a better option for you. If you're a die-hard juice drinker, stick to juice. If you want fizzy juice, add a little seltzer to your fruit juice.
Example Output: 2

Example Input: I found it so hard to believe anyone could give this mix 1 star, I had to read those reviews. Two of them seem like ads for Robs Red Mill, and the other one didn't make any sense. You must be looking for pancakes or waffles, so do yourself a favor and give these a go. They are delicious
