Yes, you definitely need to read the question thoroughly. And any question that teaches people that they need to read things thoroughly before committing oneself to a course of action based on what was read must be a very good question.
I didn't read thoroughly enough: just saw the required output and thought "oh, that's matrix"; didn't notice how the output had to be the produced. Ouch! Definitely a good question!
