说明： 用遗传算法解决vrp问题，源码加详细文档说明 很有用的哦(algorithm for multi-
objective optimization. It is a very e® ective algorithm but has been generally
criticized for its computational complexity)

HuffanCoding
读取数据，统计所得到的文件中每个字母的权值，创建哈夫曼树，哈夫曼编码。哈夫曼解码，解码后内容写入到指定的文件。
读取数据里面的内容是由英文单词组成。读取文件的时候传入文件存放的路径、读取方式以及读出以后存放的数组，最终可以得到一个存放目标文件内容的数组。
将得到的数组进行字母权值的统计，统计每个字母出现的次数，次数即为每个字母的权值。
将得到的字符数组与权值数组作为创建哈夫曼树的依据，哈夫曼树根据每个字母权值的大小来创建，每个节点，包括权值、父节点、左子、右子和字母本身。
根据哈夫曼树进行编码。形成目标文件的哈夫曼编码，将此编码返回。
根据哈夫曼树得到的数组即为解码数组，解码数组作为解码的结果返回。
写入输出文件，将解码得到的数组、文件的完整路径以及文件的写方式作为参数传入，将数组写入到相应的文件中。
(Read the data, statistical documents obtained weights for each letter, create a Huffman tree, Huffman coding. Huffman decoding, the decoded contents are written to the specified file.
Read the content inside is composed of English words. When the incoming file to read the file storage path, read mode and read out after storage array that can eventually get a storage target file contents of the array.
The resulting array of letter weights statistics, statistical number of occurrences of each letter, the number is the weight of each letter.
The resulting character array with the weights array as the basis for creating Huffman tree, Huffman tree based on the size of the weights of each letter to create, for each node, including weights, parent, left child, right child, and letter itself.
According to Huffman coding. The formation of the target file Huffman coding, this code returns.
According to Huffman decoding the resulting array is an array, the decoder decodes the result is retur)

student
定义两个类，techer类和student类，将student类对象转换为techer类对象，假设学生毕业后留校，其相关
数据仍然有用，如编号num，姓名name，性别sex。转换后输出相关数据(Define two classes, techer class and student class, the student class object is converted to techer class object, assuming that the students stayed after graduation, the related data is still useful, such as the number num, name name, sex sex. The converted output data)

Matrix multiplication problem is a typical example of dynamical programming.
Suppose you have to evaluate an expression like A*B*C*D*E where A,B,C,D and E are matrices. Since matrix multiplication is associative, the order in which multiplications are performed is arbitrary. However, the number of elementary multiplications needed strongly depends on the evaluation order you choose.
For example, let A be a 50*10 matrix, B a 10*20 matrix and C a 20*5 matrix.
There are two different strategies to compute A*B*C, namely (A*B)*C and A*(B*C).
The first one takes 15000 elementary multiplications, but the second one only 3500.
Your job is to write a program that determines the number of elementary multiplications needed for a given evaluation strategy.
