My issue

include
using namespace std;

int main() {
// your code goes here
int t;
cin>>t;
while(t–)
{
int n;
cin>>n;
int a[n];
for (int i=0;i<n;i++)
{
cin>>a[i];
}
for(int i=0;i<n;i++)
{
int f=1;
for (int j=0;j<n;j++)
{
if(a[i]==a[j] && i!=j)
{
f++;
}
}
if(f%2!=0)
{
cout<<a[i]<<“\n”;
}
}
}
return 0;
}

why I am getting the wrong answer??

My code

#include <iostream>
using namespace std;

int main() {
	// your code goes here
	int t;
	cin>>t;
	while(t--)
	{
	    int n;
	    cin>>n;
	    int a[n];
	    for (int i=0;i<n;i++)
	    {
	        cin>>a[i];
	    }
	    for(int i=0;i<n;i++)
	    {
	        int f=1;
	        for (int j=0;j<n;j++)
	        {
	            if(a[i]==a[j] && i!=j)
	            {
	                f++;
	            }
	        }
	        if(f%2!=0)
	        {
	            cout<<a[i]<<"\n";
	        }
	    }
	}
	return 0;
}

@tushar_rao210
U have to print break after printing the answer to get out of the loop;
like this

#include <iostream>
using namespace std;

int main() {
	// your code goes here
	int t;
	cin>>t;
	while(t--)
	{
	    int n;
	    cin>>n;
	    int a[n];
	    for (int i=0;i<n;i++)
	    {
	        cin>>a[i];
	    }
	    
	    for(int i=0;i<n;i++)
	    {
	        int f=1;
	        for (int j=0;j<n;j++)
	        {
	            if(a[i]==a[j] && i!=j)
	            {
	                f++;
	            }
	        }
	        if(f%2!=0)
	        {
	            cout<<a[i]<<"\n";
	            break;
	        }
	    }
	}
	return 0;
}
