Consider the twos complement addition of two n$-$bit numbers:

zn$-1$zn$-2$ c z$0=$ xn$-1$xn$-2$ c x$0+$ yn$-1$yn$-2$ c y$0$

Assume that bitwise addition is performed with a carry bit ci generated by the addition of xi

$,$ yi

$,$ and ci$-1.$ Let n be a binary variable indicating overflow when n $=1.$ Fill

in the values in the table
