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.

Example Input: Only 5mg sodium per serving, chips are crisp. I sometimes will dip in a low salt ketchup and that adds a bit to the flavor.
Example Output: 5

Example Input: The coffee pods are convenient but the quality of the coffee is not good (you will find this especially if you are used to using a grinder, fresh beans etc). I'm not sure if this is due to the pod itself or the machine in terms of temperature, pressure. I suspect the problem lies with the pod technology and the coffee within. I'm going back to a grinder, fresh beans and a traditional machine.
Example Output: 2

Example Input: I like the item or I would not have ordered it, However, I ordered 100 and 100 was confirmed. When the order arrived it contained only 96, four short. Rather skimpy. I usually like to receive what I ordered and for which I paid full price.
Example Output:
5
