In this task, you're given a review from Amazon's food products. Your task is to generate a rating for the product on a scale of 1-5 based on the review. The rating means 1: extremely poor, 2: poor, 3: neutral or mixed, 4: good, 5: extremely good. 

Input: Consider Input: There should be an option for a 0 star rating because that is what I would rate this item. First, the sampling was to include 9 varieties but included only 7.  It appears that the two flavors out of stock were not substituted with two other flavors but instead a few more of the remaining flavors were tossed in the box. I had expected that when a limited edition coffee flavor such as Island Coconut was out of stock, it would be replaced with a different limited edition coffee flavor.  Same thing for the Half and Half Lemonade. Second, the order was not balanced.  Of the 7 flavors I did receive, only 2 were coffees, the remaining 5 were teas. The concept of a summer sampler set is a good one but the execution here was an epic fail.  The order is being returned today.

Output: 1


Input: Consider Input: Raving reviews made me buy this for dogs. I have a lab mix a beagle and 2 Shepards that I got from impoundment and they're not spoiled. One chewed it to crumbles but left it on the ground and my Shepards have been burying them in the backyard. I wasted my money on this one.

Input: Consider Input: Roland S&B sardines are the best you can buy and believe me,  I've tried them all.  ALSO....Amazon's price is half what I had been paying.
