I'm reminded of a quotation from Monique's father.

Do you know how the syntax of the Java language? This assignment almost
telling you exactly what it is you're supposed to type in. There's almost
not "thinking" or problem solving involved here; it's just memorization of
the rules of writing a legal Java program.

The hint gives one approach, but I'd probably use string manipulation
functions rather than modding and dividing. Choose whichever approach is
clearer to you.

Good luck.
