68. 4-bit Comparator

How do you plan to solve it?

/*Write your code here*/

module maxmin4 (
    input [3:0] a,b,c,d,
    output [3:0] max, min
);

wire [3:0] maxab,maxcd,minab,mincd;

assign maxab = (a>=b) ? a : b;
assign maxcd = (c>=d) ? c : d;
assign minab = (a<b) ? a : b;
assign mincd = (c<d) ? c : d;

assign max = (maxab >= maxcd) ? maxab : maxcd; 
assign min = (minab < mincd)  ? minab : mincd;
