Min, Max and Sum

Write a program which reads a sequence of $n$ integers $a_i (i = 1, 2, ... n)$, and prints the minimum value, maximum value and sum of the sequence.

Input

In the first line, an integer $n$ is given. In the next line, $n$ integers $a_i$ are given in a line.

Output

Print the minimum value, maximum value and sum in a line. Put a single space between the values.

Constraints

$0 < n \leq 10000$

$-1000000 \leq a_i \leq 1000000$

Sample Input

5
10 1 5 4 17

Sample Output

1 17 37

Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);

		int num = sc.nextInt();//整数の数
		int n[] = new int[num];//配列
		long sum = 0;
		int max = n[0];//最大値
		int min = n[0];//最小値

		//配列の格納
		for (int i = 0; i < n.length; i++) {
			int x = sc.nextInt();//格納する数字
			n[i] = x;

		}

		for (int i = 0; i < n.length; i++) {

			//最大値
			if (max < n[i]) {
				max = n[i];

			}

			//最小値
			if (min > n[i]) {
				min = n[i];

			}

			//初回のみ最大値と最小値の入力
			if (i == 0) {
				max = n[i];
				min = n[i];
			}

			//合計
			sum = sum + n[i];
		}
		//出
		System.out.println(min + " " + max + " " + sum);
	}
