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.lang.reflect.Array;
import java.math.BigDecimal;
import java.util.*;
import java.util.stream.Stream;

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

        int num = sc.nextInt();
        ArrayList<BigDecimal> list = new ArrayList<BigDecimal>();

        for(int i=0; i<num; i++){
            list.add(sc.nextBigDecimal());
        }

        BigDecimal sumnum = new BigDecimal(0);

        for (BigDecimal e : list) {
            sumnum = sumnum.add(e);
        }

        Optional<BigDecimal> maxnum = list.stream().max(Comparator.naturalOrder());
        Optional<BigDecimal> minnum = list.stream().min(Comparator.naturalOrder());

        minnum.ifPresent(n -> System.out.print(n + " "));
        maxnum.ifPresent(n -> System.out.print(n + " "));
        System.out.println(sumnum);
    }
}
