编程题：String Builder

You are going to read four numbers: n, a, b and c, like this:

```
12 2 5 3
```

First, *n* is used to build up a string from 0 to n, like this:

```
0123456789101112
```

is a string build up for *n=12*.

Then, in all the digits from index *a* to index *b*, count the appearence of *c*.

For the string above, *2 5* is:

```
2345
```

Thus the appearence of *3* is 1.

### Input Format:

### Output Format:

One number represnets the length of the generated string.
One number represents the apprence of *c*.
There is a space between the two numbers.
