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: Wrong Answer)

import java.util.Scanner;
class Main {
	int max = -1000000,min = 1000000;
	public void min() {
		Scanner sc = new Scanner(System.in);
		long sum = 0;
		int n = sc.nextInt();
		if(n == 0) {
			max = 0;
			min = 0;
		} else if (n == 1) {
			int ai = sc.nextInt();
			if(ai > max) {
				max = ai;
				min = 0;
				sum += ai;
			} else if (ai < min) {
				max = 0;
				min = ai;
				sum += ai;
			}
		} else {
			for(int I = 1; I <= n; I++) {
				int ai = sc.nextInt();
				if(ai > max) {
					max = ai;
				} else if(ai < min) {
					min = ai;
				}
				sum += ai;
			}
		}
		System.out.println(min + " " + max + " " + sum);
	}
	public static void main(String[] args) {
		new Main().min();
	}
}
