That isn't a "puzzler", in any way, shape or form. It is quite literally "write the most basic, simple, trivial program possible". There is no trick to it, no gotcha, no special information that makes it suddenly go from hard to easy. It is always easy, and is a practical test of actual programming knowledge.
I didn't mean to imply it was hard. As to a test of programming knowledge, I'm glad I'm not in a position where I'm exposed to people who would fail such a test :)
