Problem:
Sorting Three Numbers

Write a program which reads three integers, and prints them in ascending order.

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

1 3 8

Solution in JAVA (judge verdict: Accepted)

import java.util.ArrayList;
import java.util.Collections;
import java.util.Scanner;

public class Main {
	public static void main(String[] args){
		Scanner scan = new Scanner(System.in);
		int a = scan.nextInt();
		int b = scan.nextInt();
		int c = scan.nextInt();
		scan.close();
		ArrayList<Integer> nums = new ArrayList<Integer>();
		nums.add(a);
		nums.add(b);
		nums.add(c);
		Collections.sort(nums);
		String answer = new String();
		answer += nums.get(0) + " " + nums.get(1) + " " + nums.get(2);
		System.out.println(answer);
	}
