Missing Two Numbers : Is my code valid according to the given constraints?

#1

package arrays;

public class ImpQuestion1 {

public static void main(String[] args) {
	int arr[] =  {1,3,4,6}; 
  MissingTwoElements(arr);
}
public static void MissingTwoElements(int [] arr )
{
	int n = arr.length;
	int brr[] = new int[n+2];
	for(int j=0;j<n+2;j++)
	{
		brr[j] = j+1;
	}
	int i=0 , count = 0 , low = 0 ; 
	while (i<n&&count<2)
	{
		if(arr[i]==brr[low]) {
			low++;
		}
		else
		{
			count++;
			System.out.println(brr[low]);
			low++;
			i--;
		}
		i++;
	}
}

}

Are the space and time complexities being fulfilled here ?

#3

No,
when you create array br you actually take up space but the constraint is to do that in unit space O(1)… So your code is incorrect .
