Hello guys,

Here’s the problem’s link.
Here’s my code in java

import java.util.*;
class ChefandDolls
{
public static void main(String[] args)
{
Scanner in=new Scanner(System.in);
int T=in.nextInt();
while(T-- > 0)
{
int N=in.nextInt();
int[] Ns=new int[N];
for(int i=0 ; i<N ; i++)
Ns[i]=in.nextInt();

        Arrays.sort(Ns);
        
        for(int i=0 ; i<N ; i+=2)
        {
            try
            {
                if(Ns[i]!=Ns[i+1])
                {
                    System.out.println(Ns[i]);
                    return;
                }
            }
            catch(ArrayIndexOutOfBoundsException e)
            {
                System.out.println(Ns[i]);
            }
        }

But it gives correct answer as 2

How many testcases are there?

Oh! damn! Now I understood the problem is with the return statement, actually the whole program terminates not just the loop, so it prints the answer for only one test case, should use break instead.

Thanks Bro!
Thanks for helping!
