This appears to be a homework question. Just as on StackOverflow, it's not ok to ask people to do homework problems for you on julia-users.

Especially when it's a discussion board that the lecturer posts regularly...

Many computer language mailing lists/forums have some policy about
homework problems. Even though most universities (and, in addition, some
specific courses) also have rules for proper academic conduct which
should preclude questions like the OP, perhaps guidelines about homework
problems should be formulated for julia-users explicitly.

In this particular case, I let the students collaborate and use outside resources as long as they cited the sources. But asking for the answer on Julia-users was not exactly what I had in mind...

Somebody recently requested an answer from me to do solve a problem in C++ (which did turn out to be homework) on SO, so instead of answering it, I gave a trivial four line (and much easier to read) solution in Julia ;-) 
(and said that was an example of why I no longer wanted to program in C++!)
(somebody else had already given a Python solution - it was nice to see that the Julia solution was simpler than the Python version)
