RunLength

java.lang.Object
- edu.princeton.cs.algs4.RunLength

```
public class RunLength
extends java.lang.Object
```
The RunLength class provides static methods for compressing and expanding a binary input using run-length coding with 8-bit run lengths.
For additional documentation, see Section 5.5 of Algorithms, 4th Edition by Robert Sedgewick and Kevin Wayne.

方法概要

修饰符和类型	方法	说明
`static void`	`compress()`	Reads a sequence of bits from standard input; compresses them using run-length coding with 8-bit run lengths; and writes the results to standard output.
`static void`	`expand()`	Reads a sequence of bits from standard input (that are encoded using run-length encoding with 8-bit run lengths); decodes them; and writes the results to standard output.
`static void`	`main(java.lang.String[] args)`	Sample client that calls `compress()` if the command-line argument is "-" an `expand()` if it is "+".
