产生泊松分布随机数的程序

acm pku的经典题目的代码和思路，包括了DP问题，贪心，回溯，等等都是很经典的题目-acm pku classic subject code and ideas, including the DP problem, greedy, backtracking, and so on are all very classic topic

一个费诺编码器,输入N个总和为1的小数,就可以得到N个费诺码-a fee Connaught encoder input N sum of a minority, it can be N Connaught yards charges

对输入的二维数组实现自组织聚类分析，入:类的个数k,样本数n:随机选取k个对象,初始化k个聚类中心;设置迭代计数器t=0;While(r≠0)把样本点分到距离最近的聚类中心所入:类的个数k,样本数n:随机选取k个对象,初始化k个聚类中心;设置迭代计数器t=0;While(r≠0)把样本点分到距离最近的聚类中心所入:类的个数k,样本数n:随机选取k个对象,初始化k个聚类中心;设置迭代计数器t=0;While(r≠0)把样本点分到距离最近的聚类中心所。

Dijkstra的推广之一： 最短路径的子路径是最短路径。证明:(算法导论P358) 次短路径的子路径是最短路或次短路.(这个是次短路径的最优子结构). 证明： 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

一个简单的计算器程序，进行简单的数学计算，正确无误-A simple calculator program to carry out simple mathematical calculations are correct

FFT算法的软件实现，有方法讲解，也有部分C++的源码。-FFT algorithm for software implementation, there are ways to explain, as well as some C++ The source.

       Dual Tone Multi Frequencies (DTMF tones) are two different tones at two ends of a spectrum that are used to send information in telephonic communication mediums. The tones represent numbers 0-9 and the symbols * and #. A series of these numbers may be assigned to individuals as points of contact, as in a phone number, or the numbers can be used to relay other sorts of information.       While it may seem confusing, it should be noted that all numbers on a telephone are assigned two DTMF tones, and in all, seven different frequencies are assigned. Some numbers will have the same lower frequency, but different higher frequency, while others will have the same higher frequency but a different lower frequency. The range is between 697 Hz and 941 Hz for the lower frequencies and 1209 Hz and 1633 Hz for

该代码用于求最大子段和，常用语大学或研究生算法课程的作业。当然，该源码是练习算法的一个很好的例子。
