	public static void main (String[] args) throws java.lang.Exception
	{
		// your code goes here
		Scanner sc=new Scanner(System.in);
	int	t=sc.nextInt();
		for(int i=1;i<=t;i++)
		{
		  int n=sc.nextInt();
		  int k=sc.nextInt();
		  if(n%4==0||n==0)
		  {
		    if(k==0)
		    {
		    System.out.println("Off");

In case if n=3 and k=0
we know that if it is in the off state then it is currently at level 4, from there we move 3 steps forward this would reach at level 3 which, is On state .
Now,
if k=1 and any value of n which is not a multiple of 4 ,we are not too sure whether it is in level 4 or any other level therefore it is marked as ambiguous.

This is the case which is not satisfied in your program.
