Tim Burton has a unique style when making his movie. I love Nightmare Before Christmas and Edward Scissorhands.”:-

There are 27 rooms that start with a 1 (100 – 126), 20 rooms with 2nd digit 1 (110 – 119 and 210 – 219), and 6 rooms that end with a 1 (101, 111, 121, 201, 211, and 221).

27+20+6 = 53

This problem amounts to counting how many numbers there are between 1 and 2010 that do not contain a 4. First consider the numbers up to 2000. There are nine possible digits other than 4 in each of the first three positions, and two possible digits in the thousands position.

2x(9^3)=1458

Finally there are nine numbers greater then 2000 without a 4.
Therefore, the answer is 1458+9=1467.

The following Java algorithm confirms the answer:

public static void main(String [] args){

int total = 0;

for (int i = 0; i <= 2010; i++)
{
String sTemp = Integer.toString(i);
int index = sTemp.indexOf(“4″);

if (index != -1){
total++;
}
}

System.out.println(“Number of numbers containing a 4: “+total);
System.out.println(“2010 – “+total+” = “+(2010-total));
}

Sequence can be visualized as:

__ __ __ __ 7! __ __ 8!

Which can be simplified to:

__ __ __ __ 5,040 __ __ 40,320

Easiest way to proceed is by using the simple algebra of geometric sequences.

To fill the gap from positions 5 to 8 we can see that:

5,040 * x = positon 6
position 6 * x = position 7
position 7 * x = position 8 = 40, 320

or simplified:

5,040 * x * x * x = 40,320

Now simply solve for x:

5,040 * x * x * x = 40,320 > 5,040 (x^3) = 40,320 > (x^3) = 8 > x=2

We now know that each position in the sequence is being doubled.
Starting at the earliest known position (postion 5 = 5,040) we can work backwards to find position one.

Postion 4 = (position 5)/2 = 5,040/2 = 2,520
Postion 3 = (position 4)/2 = 2,520/2 = 1,260
Postion 2 = (position 3)/2 = 1,260/2 = 630
Postion 1 =( position 2)/2 = 630/2 = 315

Therefore, postion 1 = 315
