问题描述

任何人都可以帮助我.
如何使用LZW算法Java语言在SMS上压缩字符串消息，然后在接收方设备上将其解压缩为原始字符串.非常感谢.

如果可以使用任何算法.

非常感谢

Can anyone help me.

采用此算法，希望对您有所帮助::)


LZW压缩算法:

take this algorithms and hope it helps u : :)


The LZW compression algorithm:

STRING = get input character
WHILE there are still input characters DO
    CHARACTER = get input character
    IF STRING+CHARACTER is in the string table then
        STRING = STRING+character
    ELSE
        output the code for STRING
        add STRING+CHARACTER to the string table
        STRING = CHARACTER
    END of IF
END of WHILE

output the code for STRING

这就是减压算法.

and this is the decompression algorithm.

Read OLD_CODE
output OLD_CODE
WHILE there are still input characters DO
    Read NEW_CODE
    STRING = get translation of NEW_CODE
    output STRING
    CHARACTER = first character in STRING
    add OLD_CODE + CHARACTER to the translation table
    OLD_CODE = NEW_CODE
END of WHILE
