$f(x, y, z)=\operatorname{ sum} (x 1, XZ, X 3) $ Here, x1, x2, X3 is the last 3 digits of your ID. (i) Design a decoder that represent this function. Set number of input and output according to the $x 1, X2, X 3$ value. (ii) Also design a multiplexer with the same function with minimum number of selectors. CS.JG.012
