Solution in JAVA (judge verdict: WA: Presentation Error)

import java.util.Scanner;

public class Main {
    public static void main(String args[]){
        Scanner sc = new Scanner(System.in);
        int a = sc.nextInt();
        int b = sc.nextInt();
        int c = sc.nextInt();
        int swap;

        if(a > b){
            swap = a;
            a = b;
            b = swap;
        }
        if(b > c){
            swap = b;
            b = c;
            c = swap;
        }
        if(a > b){
            swap = a;
            a = b;
            b = swap;
        }

        System.out.printf("%d %d %d", a, b, c);
    }
