##### Woburn Challenge 1995

The factorial of a whole number (written as ) is defined as follows:

For example, .

The "factorial length" of a number is defined as the number of digits
in . Thus the factorial length of 10 is 7.

#### Input Specification

On each of five lines is a positive integer in the range .

#### Output Specification

For each of the five inputs, output that number's factorial length in the format shown below.

#### Sample Input

```
1
2
5
10
52
```

#### Sample Output

```
The length of 1! is 1
The length of 2! is 1
The length of 5! is 3
The length of 10! is 7
The length of 52! is 68
```
