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)

设有一头指针为L的带有表头结点的非循环双向链表,其每个结点中除有prev(前驱指针),data(数据)和next(后继指针)域外,还有一个访问频度域freq。在链表被起用前,其值均初始化为零。每当在链表中进行一次Locate(L,x)运算时,令元素值为x的结点中freq域的值增1,并使此链表中结点保持按访问频度非增(递减)的顺序排列,同时最近访问的结点排在频度相同的结点的最后,以便使频繁访问的结点总是靠近表头。试编写符合上述要求的Locate(L,x)运算的算法,该运算为函数过程,返回找到结点的地址,类型为指针型。(Has a head pointer is non-circular doubly linked list L with a header node, each node in addition to prev (precursor pointer), data (data) and next (successor pointers) outside, there is an access frequency degree domain freq. Before the list was hired, their values are initialized to zero. Whenever carried out in the list once Locate (L, x) when the operation, so that the element node x is the value in freq domain by one, and keep this list in the node-access frequency of non-increasing (decreasing) the order, while a recent visit to the nodes in the same row of the frequency of the last node, so that the nodes are frequently accessed tables are always near the head. Locate (L, x) algorithm is prepared in accordance with the above requirements of the test operation, the operation as a function of the process, return to find the address of the node of type pointer.)
