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);
    
    wire [3:0] max1 = (a > b) ? a : b;
    wire [3:0] max2 = (c > d)? c : d;
    wire [3:0] min1 = (a < b)? a : b;
    wire [3:0] min2 = (c < d)? c :d;
    assign max = (max1 > max2)? max1 : max2;
    assign min = (min1 > min2)? min2 : min1;
