Construct an SM block that has three input variables $,$ A$,$B and $C,$ four outputs

$(W,X,Y,$ and $Z),$ and two exit paths. For this block, output $Z$ is always $1,$ and $W$ is $1$

iff A and $B$ are both $1.$ If $C=1$ and $A=0,Y=1$ and exit path $1$ is taken. If $C=0$

or $A=1,x=1$ and exit path $2$ is taken.
