PRG/420 Week 2 Java 2.20 LAB: 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, I-405 services I-5, and I-290 services I-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:
I-90 is primary, going east/west.
Ex: If the input is:
290
the output is:
I-290 is auxiliary, serving I-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.
