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);
    assign OUT[7:4]=A[3:0];
    assign OUT[3:2]=B[1:0];
    assign OUT[1]=~C;
    assign OUT[0]=D;
