Problem 24. Function Iterator

Hey, I finished the cody challenge a few months ago but when I just checked back my old solution to this problem is no longer valid! So my solution was retroactively rejected! What gives Cody team?

Yes... sorry about that. It turns out the STR2FUNC function was being badly abused in the name of writing short answers. Since we saw almost no places where it was being used responsibly, we decided to invalidate all answers with STR2FUNC. It's a compromise, but we think on balance that it's the right thing to do.
