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 C# (judge verdict: Accepted)

using System;

public class Program
{
	public static void Main(string[] args)
	{
		var ss = new StreamScanner();
		//---------------------------------
		var n = ss.Next<int>();
		long[] a = ss.Next<long>(n);
			long sum = 0;
			for (int i = 0; i < n; i++)
			{
				sum += a[i];
			}
		long max = long.MinValue;
			for (int i = 0; i < n; i++)
			{
				if (max < a[i])
				{
					max = a[i];
				}
			}
		long min = long.MaxValue;
			for (int i = 0; i < n; i++)
			{
				if (min > a[i])
				{
					min = a[i];
				}
			}

			Console.WriteLine(min + " " + max + " " + sum);

		/*
		//????????????int, double, string?????????????????£????????????
