把中缀表达式转换成后缀表达式，输入中缀表达式输出后缀表达式-Chinese sergeant expressions into expressions suffix, the importation of Chinese exports suffix sergeant expression expression

利用哈夫曼编码进行通讯可以大大提高信道利用率，缩短信息传输时间，降低传输成本。但是，这要求在发送端通过一个编码系统将待传数据进行预先编码；在接受端将传来的数据进行解码（复原）。对于可以双向传输的信道，每端都要有一个完整的编/译码系统。试为这样的信息收发站写一个哈夫曼的编译码系统。（难易程度：高）

求最短路径，基于VISUAL C++开发的源代码 属于数据结构-Seek the shortest path, based on the VISUAL C++ Developed source code belonging to the data structure

栈(stack)是程序设计过程中经常遇到朝气一种数据结构形式，它对于数据的存放和操作有下面这样的特点： 1) 它只有一个对数据进行存入和取出的端口； 2) 后进者先出，即最后被存入的数据将首先被取出。其形式很象一种存储硬币的小容器，每次只可以从顶端压入一个硬币，而取出也只可以从顶端进行，即后进先出。 这样的数据存储和管理形式在一些程序设计中很有用。例如，编译系统中(这是一类比较复杂的程序)，对于函数调用的处理、对于表达式计算的处理，都利用了栈这样的数据结构。- The stack (stack) is in the programming process frequently meets the vitality one kind of construction of data form under, it has such characteristic regarding data depositing and the operation: 1) it only has a logarithm according to the port which carries on stores and takes out; 2) less advanced first leaves, namely finally the data which will store first is taken out. Its form looks like one kind of memory coin very much the small container, each time only may press in a coin from the peak, but takes out also only may carry on from the peak, namely less advanced first leaves. Such data storage and the management form are very useful in some programmings. For example, in the compiling system (this is a kind of quite complex procedure), transfe
