Edit: this is a D flip-flop, thanks!

The figure below shows the input D to a flip-flop (consisting of a pair of latches, as shown on Lecture 13, Slide 34), along with the clock control input, clk. Assume that the output, Q, is initially 0. Fill in the blanks below, indicating the output, Q, at time instants 1, 2, and 3. Note: the question concerns the Q output of the second latch, .e., the final Q output of the whole combination. clk 2 3 1 2: 3
