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. 

Ex Input:
Go to Costco, and you can buy lower than this  price per oz. Currently $32 ($3 off regular $34.99)+ tax for big size = 0.83$/oz.  Besides, it is more convinient to return if you kid does not like this formula  Be careful, many times some sellers over price a product, and still make the product rank in the best sellers.

Ex Output:
1


Ex Input:
We have three large dogs - two malamutes and a husky mix. I'd read a few of the reviews on here that said that these treats were only good for large dogs, so I figured they'd be perfect for my three chow hounds. Unfortunately these are much smaller than I thought they were. Two, three bites tops and my dogs would have them down, and they didn't seem to like them as much as they like their regular bones (cheap, regular bones). So, nope, I don't think that these are that great, and apparently neither did my dogs.

Ex Output:
2

i have used the icicle a few times, and it sounds great! everything works how it's supposed to, and it is a very simple but efficient interface. the ONLY thing that i can see that's wrong with it, is it just feels light and cheap. granted its only around $40 so you can't expect too much from it. the plastic just feels rather cheap. but i plan on treating it very nicely and gently anyways so all in all i don't foresee a major problem on that front.
