合并果子，压缩是一种有效的减小数据量的方法，目前已经被广泛应用于各种类型的信息系统之中。



一种压缩文本文件的方法如下：



1. 原始文本文件中的非字母的字符，直接拷贝到压缩文件中；



2. 原始文件中的词（全部由字母组成），如果是第一次出现，则将该词加入到一个词的列表中，并拷贝到压缩文件中；否则该词不拷贝到压缩文件中，而是将该词在词的列表中的位置拷贝到压缩文件中。



3. 词的列表的起始位置为 1 。 词的定义为文本中由大小写字母组成的最大序列。大写字母和小写字母认为是不同的字母，即 abc 和 Abc 是不同的词。词的例子如下： * x-ray 包括两个词 x 和 ray * mary s 包括两个词 mary 和 s * a c-Dec 包括三个词 a 和 c 和 Dec 编写一个程序，输入为一组字符串，输出为压缩后的文本。-Fruit combined compression is an effective method for reducing the amount of data, has been widely applied to various types of information into the system. A method of compressing a text file is as follows: 1 original text file non-alphabetic characters, copy directly to the compressed file　2 words in the original document (all composed of letters), if it is the first time, then. The word is added to a word list, and copied to the compressed file　otherwise the term is not copied to the compressed file, but the position of the word in the list of words copied to the archive. 3 the starting position is a list of words. The maximum term is defined by a sequence of text consisting of uppercase and lowercase letters. Uppercase and lowercase letters are considered different letters, ie abc and Abc are different words. Examples of the word as follows:* x-ray consists of two words x and ray* mary' s, including two words mary and s* a c-Dec consists of three words a and c and Dec to write
