Build a miniALU using custom component of nandgame: The first screenshot shows the table with f0-f2 are control bits. a and b are two 16-bit inputs. The second screenshot is the suboptimal answer

The adder and subtractor have to be merged, using only 1 add16 gate. Use 2 compliments for subtraction a+not(b)+1 and put 1 to the carry bit of adder16. 8-way mux can be done using select 16 gates. Please screenshot the answer using Nandgame.
