Hello I have following question and it says:

I basically cannot understand this solution.

My questions:

1. isn't it a sequence of 4 0s followed by 4 1s? (answer says 4 1s followed by 4 0s) since retangle below the middle line represent 0 in NRZ?

2. if you see the middle of those rectangle block, I think there is one transition (from what I learned, definition of transition is something that happens when there exists 0->1 or 1->0) at circled area shown in following picture:

3. Also above figure looks like polar NRZ but not NRZ. is that really correct drawing?

But why is answer saying that there are no transitions?

Thank you very much.
