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 {carry,sum} = a + b;
    
endmodule

// Full Adder using 2 Half Adders
module full_adder_struct (
    input  a, b, cin,
    output sum, cout
);
    // Write code here
    wire w1,w2,w3;
    half_adder H0(a,b,w1,w2);
    half_adder H1(w1,cin,sum,w3);

    assign cout = w3 | w2;

endmodule
