Wrong answer in unique numbers - ii question

#1

While compiling it I keep getting the right answer but when I submit none of the test cases have passed.
Here’s my code - https://ide.codingblocks.com/s/245834

#2

code is fine . check this condition before syso line
if(x>y)
System.out.println(y+ " " + x);
else
System.out.println(x + " " + y);

#3

import java.util.*;
public class Main {
public static void uniqueNum(int[] arr){
int xor = arr[0];

	for(int i=1;i<arr.length;i++){
		xor ^= arr[i];
	}

	int rightMostBit = xor & ~(xor-1);

	int x = 0;
	int y = 0;

	for(int i=0;i<arr.length;i++){
		if((arr[i] & rightMostBit) != 0){
			x ^= arr[i];
		}
		else{
			y ^= arr[i];
		}
	}
	if(x>y)
	System.out.println(y+ " " + x);
	else	System.out.println(x + " " + y);
}
public static void main(String args[]) {
    // Your Code Here
	Scanner sc = new Scanner(System.in);
	int n = sc.nextInt();
	int[] arr = new int[n];
	for(int i=0;i<n;i++){
		arr[i] = sc.nextInt();
	}
	uniqueNum(arr);
}

}
