Unique Number - I

[Sejalrathi]

import java.util.*;
public class Main {
public static void main(String args[]) {
Scanner s = new Scanner(System.in);
int n = s.nextInt();
int []arr = new int [n];
for (int i = 0 ; i < n ; i++){
arr[i] = s.nextInt() ;
}
int z = 0 ;
for (int i = 0 ; i < n ; i++){
z = z ^ arr[i] ;
}
System.out.println(z + “is present only once”);
}
}
What is wrong in this code ?
It is not passing both the testcases though I m getting right answer .

@Sejalrathi,

Error: You don’t need to print “is present only once” in the answer. Just print what is shown in the output of the question
