Write code in Coral Laungae $-$ 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.
