A) Build 4-bit ring counter by using D flip-flops and 2x1

A) Build 4-bit ring counter by using D flip-flops and 2x1 MUX's so that when select input is 0 it shifts right, when 1 it shifts left. What are the possible initial states for the ring counter? B) If accidentally our ring counter starts with state 0110 in shift right mode, write the next states for 4 clock cycles of the ring counter
