i just need a final answer

9 For the given circuit, if you know that initially Q = 0 and W = 0010 in the next four clock cycles (from left to right), then find the sequence of the output (Z). Note: type the result without any additional spaces, characters, etc... * (3.5 Points) Dolo lo T-FF Q 2x4 Decoder D1 Dzb D367 W z clk 0000 Assume an 8-bit regular down counter with the current state 01010100, how many flip flops will complement (flip) its current state to achieve the next count? Write your answer without any additional characters. *
