A combinational circuit is divided into two sub-circuits N1 and N2 as shown.

The sub-circuit N1 performs the division of the binary number ABC by two. The outputs E and D represent the quotient (result) of the division and F represents the remainder.

The sub-circuit N2 has Z as an output. Write the expression of Z in terms of D, E, and F as sum of product. Complete the truth table of the circuit.
