17. Binary to Gray Code Converter

How do you plan to solve it?

/*Write your code here*/
module bin2gray4 (
    input [3:0] bin_in,
    output [3:0] gray_out
);

//Write as behavior
//assign gray_out = {bin_in[3],(bin_in[3]^bin_in[2]),(bin_in[2]^bin_in[1]),(bin_in[1]^bin_in[0])};

//Clean code
    assign gray_out = (bin_in>> 1) ^ bin_in;
