GBK，unicode utf-8 编码转换工具(Encode Convert Tool between GBK,unicode utf-8,url)

读取一个文本文件（英文，ASCII编码），对出现的单词次数进行统计，并按照出现次数从低到高排序，输出到一个文本文件中（每行一个单词信息，格式：单词 出现次数）。采用二叉树结构存储，中序遍历，快速排序。(Reads a text file (English, ASCII encoding), the number of occurrences of the word statistics, and in accordance with the number of occurrences of the sort low to high, output to a text file (one word per line message format: word occurrences). Binary tree structure stored in preorder, quick sort.)

说明：  能够实现起泡法，二分法，堆排序，插入排序，选择排序，快速排序六种方法对100个数进行排序的时间空间复杂度进行比较(To achieve foaming method, dichotomy, Heap Sort, Insertion Sort, Selection Sort, Quick Sort six methods on 100 the number of sort of time and space complexity comparison)
