	int [] arr = new int [n];
	for(int i = 0 ; i< n ; i++)
	{
		arr[i] = sc.nextInt();
	}
	System.out.println(SubarraysDE(arr));
}

public static int SubarraysDE( int[] arr )
{
    int j = 0 ;
    int ans = 0;
    HashSet< Integer > map = new HashSet<>();
    for(int i = 0 ; i<arr.length ; i++)
    {

        while( j < arr.length  && map.contains(arr[j]) == false )
        {
            map.add(arr[j]);
            j++;
        }
		            ans = ans + (map.size()*(map.size()+1)/2);

        
        map.remove(arr[i]);


    }

    return ans;
}

}

hope this will help u
pls rate my work
