11. Vector Concatenation

How do you plan to solve it?

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