64. Full Adder

How do you plan to solve it?

// Half Adder primitive
module half_adder (
    input  a, b,
    output sum, carry
);
    // Write code here
    assign sum = a ^ b;
    assign carry = a & b;
    
endmodule

// Full Adder using 2 Half Adders
module full_adder_struct (
    input  a, b, cin,
    output sum, cout
);
    
    wire f1,f2,f3;
    // Write code here
    half_adder ha1(a,b,f1,f2);
    half_adder ha2(f1,cin,sum,f3);

    assign cout = f3 | f2;
    


endmodule
