A computer needs to control a robot, where the computer sends the following commands:

Do nothing


00

Turn right


01

Turn left


10

Move forward 11



You have to design a circuit that accepts these commands and sends the robot the following signals

Do nothing


000


Turn right


001


010


011

Turn left


101


110


111

Move forward 100


100




So they respectively take 1,3,3 and 2 clock cycles. Until the current command is completed, don't take a look at the next input from the computer.
