	public static void main(String[] args) {
    boolean[] arr = new boolean[500];
    for(int i =0; i<arr.length; i++) {
	  arr[i] = true;
    }

   int leftCount = 500;
   int countNum = 0;
   int index = 0;

   while(leftCount >1) {
	   if(arr[index] == true) {
		 countNum++;
	   }
	   if(countNum == 3) {
		 countNum = 0;
		 arr[index] = false;
		 leftCount--;
	   }
	   
	   index++;
	   if(index>499) {
		 index = 0;
	    }
    }

   for(int i=0; i<arr.length;i++) {
	    if(arr[i] == true) {
		    System.out.println(i);
		   System.exit(0);
