& n = in.nextInt();
& int []supp = new int[n];
& System.out.print("Enter "+n+" marks: ");
& for (int i=0;i<n;i++){
& double temp;
& temp=in.nextDouble();
& if ((temp%1!=0)||(temp<0)){
& System.out.println("Mark error "+temp+" try again!");
& i--;
& }
& else supp[i]=(int)temp;
& }
& int max=0;
& int min=Integer.MAX_VALUE;
& for (int i=0;i<n;i++){
& if (supp[i]>max)
& max=supp[i];
& if (supp[i]<min)
& min=supp[i];
& }
