Hmm. This smells like homework.
What problem are you trying to solve? Explain what steps you have taken and perhaps we can help you solve the problem. Your code fragment doesn't run (I suspect -- since there's no ';' after use strict) and you never read the user's input.
Come back with more effort and we'll see what we can do for you.
