可以实现模拟键盘，驱动级的。可以当普通键盘一样使用(Can realize analog keyboard, driver class. Like an ordinary keyboard can be used)

说明：  构造最小生成树的常用方法是Prim算法与Kruskal算法，二者都是基于贪心算法设计侧略。(Construction of the commonly used minimum spanning tree algorithm is Prim and Kruskal algorithms, both are based on the design side of a little greedy algorithm.)

说明：  a)需求分析： 任务：建立南京主要公交线路图。 要求：输入任意两地点，给出最佳的乘车线路和转车地点。 b)概要设计： 本程序所使用的数据结构是树和线性表，所使用的算法主要有堆排序、赫夫曼算法。 (a) Requirements Analysis : Mandate : the establishment of the Nanjing main transit route map. Requirements : 2 importation arbitrary locations, is the best car lines and interchange locations. B) Summary of design : the procedures used by the data structure is linear tree and table, the algorithm used by the main sculpture, in order Huffman algorithm.)

有的科技图书会附有索引，其中列出书中重要术语出现的页码，便于读者查看。试设计一个类似的程序。输入是一个英文文本文件，输出是文件中关键字及其出现的行号的列表并按照关键字有序排列。程序运行方式：>index inputfile keys outputflie (Some books will be accompanied by technology index, which lists important terms appear in the book pages, easy to readers to view. Try to design a similar procedure. English text input is a file, the output is a file that appears in the keywords and their line numbers list and ordered according to keywords. Program run mode:> index inputfile keys outputflie)
