Input

Three integers separated by a single space are given in a line.

Output

Print the given integers in ascending order in a line. Put a single space between two integers.

Constraints

1 ≤ the three integers ≤ 10000

Sample Input 1

3 8 1

Sample Output 1

1 3 8

Solution in JAVA (judge verdict: Wrong Answer)

import java.util.Arrays;
import java.util.Scanner;

class Main {
	Scanner sc = new Scanner(System.in);

	public void run() {
		int[] num = new int[] { sc.nextInt(), sc.nextInt(), sc.nextInt() };
		Arrays.sort(num);

		ln(StringUtils.join(num, " "));
	}

	public static void main(String[] args) {
		new Main().run();
	}

	public static void pr(Object o) {
		System.out.print(o);
	}

	public static void ln(Object o) {
		System.out.println(o);
	}

	public static void ln() {
		System.out.println();
	}
}

class StringUtils {
	public static String join(int[] array, String separator) {
		StringBuilder str = new StringBuilder(array[0] + "");
		for (int i = 1; i < array.length; i++) {
			str.append(separator).append(array[1] + "");
		}
		return str.toString();
	}

	public static String join(Object[] array, String separator) {
		StringBuilder str = new StringBuilder(array[0] + "");
		for (int i = 1; i < array.length; i++) {
			str.append(separator).append(array[1] + "");
		}
		return str.toString();
	}
