I don’t quite understand the purpose of this lesson. I had no trouble actually doing the exercises, but the way row-major order is introduced makes it sound like it’s something new, but it seems like this is just what we’ve done before. Am I missing something?

I would say the same thing especially with that last task… why is it when u put in outer.length it prints 6 numbers when in reality there should be 3 because there are 3 rows and 6 should be for the inner??
