Write a math application, which will ask user to type in 3 inputs. Input1 is

an integer A, input2 is a String, input3 is an integer B. Once the user type in the 3 integers, the

calculator should calculate and print out the result based on the follow cases:

If input2 = “Plus”, result = A+B

If input2 = “Multiply”, result =A*A

If input2 = “Minus”, result =A/B

In this question, you only consider integers on input and output. No double, or float number type

need to be considered. (hint: switch)

For example, this application should have following process:

Please enter your 3 inputs:

? 1

? Plus

? 2

Results is: 3

Please enter your 3 inputs:

? 2

? Multiple

? 5

Results is: 10
