Given the task definition, example input & output, solve the new input case.
In this task, you're given a review from Amazon. 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, 4: good, 5: extremely good.
Example: These are junk! Both bulbs have burned out within a two month period!! I cannot believe that this company can be in business with such poor quality. I have used infrared lights for my ball python for many years now and I get a varied range of months from a bulb, but I have never gone through two bulbs in a matter of two months! I am very disappointed.
Output: 1
The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, he gave 1 star to the review considering it extremely poor

New input case for you: Lens size is large, 4 x 2 Weight is 4 oz, 1 lighter than a smaller one I have the is probably glass.No little bump with higher magnification which I find annoying when trying to read. Good for Right or Left Handed use. Weight is 4 oz, 1 oz lighter than another I use with lens that is probably glass. Problem is that the surface is not precision shaped, so test appears wavey. Not a big problem , but gets distracting with expended use.
Output:
3
