IMPORTANT $($Asumme that the subtrahend$>$ minuend.$)$

using full adders and logic gates contruct a logic circuit that performs $4$bit subtraction using $2\text{'}$s complement. Use $[$M$3,$ M$2,$ M$1,$ M$0]$ for muniend, $\{$S$3,$s$2,$S$1,$S$0\}$ for subtrahend, $[$D$3,$D$2,$D$1,$D$0]$ for difference, Cin and Cout. $($Asumme that the subtrahend$>$ minuend.$)$
