11. Vector Concatenation

How do you plan to solve it?

/*Write your code here*/
module concat8_packer(
    input [3:0] A, 
    input [1:0] B, 
    input C, 
    input D, 
    output [7:0] OUT

);
wire nc;
not(nc,C);
assign OUT[7:4] = A;
assign OUT[3:2] = B;
assign OUT[1] = nc;
assign OUT[0] = D;
endmodule
