LZW

- edu.princeton.cs.algs4.LZW

```
public class LZW
extends java.lang.Object
```
The LZW class provides static methods for compressing and expanding a binary input using LZW compression over the 8-bit extended ASCII alphabet with 12-bit codewords.
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 8-bit bytes from standard input; compresses them using LZW compression with 12-bit codewords; and writes the results to standard output.
`static void`	`expand()`	Reads a sequence of bit encoded using LZW compression with 12-bit codewords from standard input; expands 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 "+".
