Design the correction circuit for a BCD adder that computes Zdigit 0 and C for S 0

Question:

Design the correction circuit for a BCD adder that computes Zdigit 0 and C for S₀. This correction circuit adds 0110 to S₀ if S₀ > 9. This is the same as adding 0AA0 to S₀, where A = 1 if S₀ > 9. Draw a block diagram for the correction circuit using one full adder, three half adders, and a logic circuit to compute A. Design a circuit for A using a minimum number of gates. The maximum possible value of S₀ is 10010.
