$(20$ points$)$ Design a combinational circuit with three inputs, $x,y,$ and $z,$ and three outputs, A$,$ B$,$ and C$.$ When the binary input is $0,1,2,$ or $3,$ the binary output is three greater than the input. When the binary input is $4,5,6,$ or $7,$ the binary output is one less than the input.

$(30$ points$)$ Design a $4-$bit binary subtractor using full adders and$/$or half adders.
