课程设计： 1.求出在一个n×n的棋盘上，放置n个不能互相捕捉的国际象棋“皇后”的所有布局。 2.设计一个利用哈夫曼算法的编码和译码系统，重复地显示并处理以下项目，直到选择退出为止。 【基本要求】 1) 将权值数据存放在数据文件(文件名为data.txt，位于执行程序的当前目录中) 2) 分别采用动态和静态存储结构 3) 初始化：键盘输入字符集大小n、n个字符和n个权值，建立哈夫曼树； 4) 编码：利用建好的哈夫曼树生成哈夫曼编码； 5) 输出编码； 6) 设字符集及频度如下表： 字符 空格 A B C D E F G H I J K L M 频度 186 64 13 22 32 103 21 15 47 57 1 5 32 20 字符 N O P Q R S T U V W X Y Z 频度 57 63 15 1 48 51 80 23 8 18 1 16 1

找一个最小的自然数，使它等于不同的两组三个自然数的三次幂之和，即找最小的x，使得：x=a*a*a+b*b*b+c*c*c = d*d*d+e*e*e+f*f*f 其中，a,b,c,d,e,f都是自然数,a<=b<=c, d<=e<=f [a,b,c]!=[d,e,f] 进一步，是否还存在另外一个自然数满足上述条件，可能的话请输出其结果

This example program is the source code for the FT232BM Test Application from our Utilities page. It can be used to test the handshaking lines on FT232BM based RS232/RS485/RS422 designs. This program can also be used for programming the external EEPROM over USB in a manufacturing environment. The test features require the test cable shown on ST_232_245.pdf to be connected. Our D2XX direct drivers should be installed for this application. The code can be modified to fit your requirements. To download the application source code , click here. To download the test cable specification, click here.

Because WDM networks are circuit switched loss networks blocking may occur because of lack of resources. Also in circuit switched networks many paths use the same links. This toolbox answers the question how different paths with different loads influence on each other and what is the blocking on each of the defined path. Toolbox is capable of computing blocking for three different WDM network types: with no wavelength conversion, with full wavelength conversion and with limited range wavelength conversion. It is worth noting that case for full conversion can be usefull for any circuit switched network without additional constraints (i.e. wavelength continuity constraint in WDM), for example telephone network. Toolbox contains also scripts for defining network structures (random networks, user defined networks) and traffic matrixes. Three graph algorithms for shortest path computation are also in this toolbox (they are used for traffic matrix creation).

Functions are mappings from one Manifold to another. Discrete Functions are functions which can be represented using a finite number of values. Given the finite extent of computer memory, algorithms which compute a function that satisfies some special properties are computing a discrete function which approximates a continuous function. Computing the function involves writing a set of equations that may be solved for the values representing the function.
