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, 1-405 services 1-5, and 1-290 services 1-90. Note: 200 is not a valid auxiliary highway because 00 is not a valid primary highway number. 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 the output is: 0 is not a valid interstate highway number. Ex: If the input is: 200 the output is: 200 is not a valid interstate highway number.

Expert Solution
Step 1

Since the no programming language is mentioned, the program is written in the JAVA language.

 

Algorithm:

1. Read the number, n.

2. IF n < 1 or n divisible by 100 or n > 999 THEN:

       Print "n is not a valid interstate highway number."

3. ELSE:

3.1. Print "I-n is ".

3.2. IF n <= 99 THEN:

       Print "primary, ".

3.3. ELSE: 

3.3.1. Print "auxiliary, serving I-(n%100), ".

3.4. IF n is even THEN:

         Print "going east/west."

3.5. ELSE:

         Print "going north/south."
