LAB: Branches: Interstate highway numbers
Primary U.S. interstate highways are numbered 1-99. Odd numbers (like the 5 or 95) go north/south, and evens (like the 10 or 90) go east/west. Auxiliary highways are numbered 100-999, and service the primary highway indicated by the rightmost two digits. Thus, the 405 services the 5, and the 290 services the 90.
Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also indicate if the (primary) highway runs north/south or east/west.
Ex: If the input is: 90
the output is: The 90 is primary, going east/west.
Ex: If the input is: 290
the output is: The 290 is auxiliary, serving the 90, going east/west.
Ex: If the input is: 0
or any number not between 1 and 999, the output is: 0 is not a valid interstate highway number.
