说明：  Euler 回路问题 .问题描述： 对于给定的图G 和G 中的2 个顶点v 和w，连接顶点v 和w 且经过图中每条边恰好1 次 的路径称为顶点v 和w 之间的1 条Euler 路。当v=w 时得到一条首尾相接的Euler 回路。 .编程任务： 对于给定的图G，编程计算图G 的一条Euler 回路。 .数据输入： 由文件input.txt 给出输入数据。第1 行有2 个正整数n 和m，表示给定的图G 有n 个 顶点和m 条边，顶点编号为1，2，…，n。接下来的m 行中，每行有2 个正整数u,v ，表示 图G 的一条边(u,v) 。 .结果输出: 将编程计算出的Euler 回路输出到文件output.txt 。如果不存在Euler 回路，则输出-1。(Euler circuit problem. Problem description : for a given graph G and G of two vertices v, w, connectivity and vertex v w map through which each side precisely the path to a meeting called vertices v, w between a Euler Road. When v = w be an end-to-end circuit Euler. . Programming tasks : for a given graph G, programming terms of a graph G Euler circuit. . Data input : from the document input.txt given input data. Line 1 has two positive integers n and m, to the graph G with n vertices and m edges and vertices numbered 1, 2, ..., n. Next m OK, every trip has two positive integer u, v, said of a graph G edge (u, v). . Results output : Programming will be calculated by Euler circuit output to a file output.txt. If there is no Euler circuit, the output 1.)

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 )

将.list后缀（地质学中常用的一种格式）的纯文本文件转换成dbf格式的vf数据库文件。 采用超线程技术，对于大尺寸的文件操作不会使界面卡死，稍作修改可成为通用的文本文件导入数据库的程序。(Will. List suffix (geology used in a format), plain text file into dbf format database file vf. The use of Hyper-Threading Technology for the large size of the file operations interface card does not die, with some slight modifications can be a text file to import generic database procedures.)
