68. 4-bit Comparator

How do you plan to solve it?

/*Write your code here*/
module maxmin4(
    input [3:0] a,
    input [3:0] b,
    input [3:0] c,
    input [3:0] d,
    output [3:0] max,
    output [3:0] min
);  

    assign max = (a>b)? ( a>c? (a>d? a:d):(c>d? c:d) ):(b>c? (b>d? b:d):(c>d? c:d));
    assign min = (a<b)? ( a<c? (a<d? a:d):(c<d? c:d) ):(b<c? (b<d? b:d):(c<d? c:d));
endmodule
