/*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,max2;
wire [3:0]min1,min2;

assign max1 = (a>b)?a:b;
assign max2 = (c>d)?c:d;


assign min1 = (a>b)?b:a;
assign min2 = (c<d)?c:d;


assign max = (max1>max2)?max1:max2;
assign min = (min1<min2)?min1:min2;
endmodule
