Write an executable script file (m-file) that takes no input and uses the switch/case structure on the function below to incorporate an user integer input (x) to give an output (y). Also, incorporate a continue command in your program code when executing the Not Allowed x values. Have your code prompt the user to add another integer input while notifying them that the value is Not Allowed.

Code is in matlab, CANNOT use elseif statements for this even though it's much easier to do so with them. Honestly just confused how to get the ranges of values I need for the cases especially because there's negative values.
