第十一届蓝桥杯JavaA成绩分析

import java.util.*;
public class Main {
	public static void main(String[] args) {
		long sum = 0,mn = 100,mx = 0,n,x;
		Scanner scanner = new Scanner(System.in);
		n = scanner.nextLong();
		for(int i = 1;i <= n;++i) {
			x = scanner.nextLong();
			sum += x;
			mn = mn < x ? mn : x;
			mx = mx > x ? mx : x;
		}
		System.out.printf("%d\n%d\n%.2f",mx,mn,sum * 1.0 / n);
	}
}

java有点太慢了。。。
