题目：某个公司采用公用电话传递数据，数据是四位的整数，在传递过程中是加密的，加密规则如下： 　　　 每位数字都加上5,然后用和除以10的余数代替该数字，再将第一位和第四位交换，第二位和第三位交换。 1.程序分析： 2.程序源代码：(Topic: a company USES the public telephone relay data, data is four integers, in the relay in the process is encrypted, encryption rules are as follows: Each Numbers add 5, then use and divided by the number of 10 instead of a remnant, then the first and fourth exchange, the second and third exchange. 1. The program analysis: 2. The source code:)

根据DFT的基二分解方法，可以发现在第L（L表示从左到右的运算级数，L＝1，2，3…M）级中，每个蝶形的两个输入数据相距B=2^(L-1)个点，同一旋转因子对应着间隔为2^L点的2^(M-L)个蝶形。从输入端开始，逐级进行，共进行M级运算。在进行L级运算时，依次求出个2^(L-1)不同的旋转因子，每求出一个旋转因子，就计算完它对应的所有的2^(M-L)个蝶形。因此我们可以用三重循环程序实现FFT变换。同一级中，每个蝶形的两个输入数据只对本蝶形有用，而且每个蝶形的输入、输出数据节点又同在一条水平线上，所以输出数据可以立即存入原输入数据所占用的存储单元。这种方法可称为原址计算，可节省大量的存储单元。附件包含算法流程图和源程序。(err)

SelfDelete(可以删除自身的VC++源码(巳通过了调试)) 为了实现程序自删除功能，我们可以通过多进程的方法解决这个问题。可执行文件在结束返回前，创建一个运行命令窗口的新进程（在Windows98中为Command进程，在Windows2000/XP中为CMD进程），当然该命令窗口以隐藏方式执行，并通过传递参数执行删除功能。为了避免可执行文件的映像还在内存中就执行删除，需要把当前进程设置为实时优先级，而命令窗口进程设置为很低的IDLE优先级，这样首先可执行文件结束返回，再运行命令窗口的删除命令，就实现了该文件自身的删除功能。 (SelfDelete (you can delete its own VC++ source code (had passed debugging)) In order to achieve the program from the delete function, we can multi-process methods to solve this problem. Return before the end of the executable file, run the command window to create a new process (in Windows98 process for the Command, in Windows2000/XP process for CMD), of course, the command window to hide the manner and to perform delete functions by passing a parameter . In order to avoid the executable file image still in memory on the implementation of delete, you need to set the current process for real-time priority, and the command window to set the process priority to low IDLE, so the end of the first return to the executable file, then run the command window delete command, the file itself to achieve the delete function. )
