Recall that a process can be stopped by typing the terminal suspend character (usually Control-Z) and can be sent a SIGCONT signal using the command kill -CONT (or implicitly, using the shell fg command).
Design a 3-bit counter, which can count either up or down. The input has a clock, and a signal U. When U = 1, the counter counts up; when U = 0, the counter counts down. For example, assume the current counter Q(t) = 011. If U(t) = 0, then Q(t+1) = 0..
