For D Flip-Flop: D = Q+

The Attempt at a Solution

In red on the picture above, I have written what I think the output will be through the first clock cycle. Next state would be 0011, but answer is 0000. Am I missing something about the D flip flop?

Ok, so it turns out I made a silly mistake, and I ended up solving the problem.

Thanks!
