有N個學生，每個學生的資料包括學號、姓名、3門課的成績，從鍵盤輸入N個學生的資料，要求打印出3門課的總平均成績，以及最高分的學生的資料（包括學號、姓名、3門課成績）
import java.util.Scanner;
public class Main {
public static void main(String[] args){
Scanner sc = new Scanner(System.in);
int n, a, b, c;
String sno, name;
int cursor = 0;
int max , suma = 0, sumb = 0, sumc = 0, mid = 0;
n = sc.nextInt();
String[][] str = new String[n][5];
for(int i = 0; i < n; i++){
sno = sc.next();
name = sc.next();
a = sc.nextInt();
b = sc.nextInt();
c = sc.nextInt();
str[i][0] = sno;
str[i][1] = name;
str[i][2] = String.valueOf(a);//返回String型別的n的值。n現在是int型別，需要想轉換成String型別，
str[i][3] = String.valueOf(b);
str[i][4] = String.valueOf(c);
max = Math.max((Math.max(a,b)),c);//找成績最大值
if(max > mid){

}
System.out.println(suma/n + " " + sumb/n + " " + sumc/n);
