Huffman编码1． 给出信源符号的一阶概率分布，并计算信源符号熵和单字符Huffman码表。2． 计算每信源的平均字长，并与信源符号熵比较。3． 比较压缩效果。-Huffman coding 1. Source symbols are given first-order probability distribution, and calculate the entropy source and single-character symbols Huffman code table. 2. Calculated the average per source word length, and entropy source comparison symbols. 3. Comparison of the effect of compression.

C语言作的四色验证1．需求分析问题描述：证明了可以用不多于4种颜色对n个区域着色，而满足相邻的区域具有不同的颜色输入形式 ： 暂定最多50个区域，如需证明更多区域，修改#define S 50 即可；以整形形式输入（取值范围1-32767）用户需要证明的区域数目，相联的一对矩阵； 输出形式：以0和1输出关联矩阵，和以blue yellow orange pink形式输出每个区域相对应证明出的颜色；-C language does four colors confirm 1. demands analyses question description: Had proven may use not to be many to 4 kind of colors to n region coloration, but satisfies the neighboring region to have the different color input form: Establishes provisionally more than 50 regions, if must prove more regions, revise#define S 50 then; Region number (value scope 1-32767) the user needs to prove which by the reshaping form input, unites a pair of matrix; Output form: By 0 and 1 output incidence matrixs, with form outputs the color by blue yellow orange the pink which each region corresponds proves;

设A和B是2个字符串。要用最少的字符操作将字符串A转换为字符串B。这里所说的字符操作包括： 1. 删除一个字符 2. 插入一个字符 3. 将一个字符改为另一个字符 将字符串A变换为字符串B所用的最少操作数称为A到B的编辑距离，极为d(A,B)。设计一个算法，计算任意两个字符串的编辑距离。 -Set A and B are two strings. Operation will use the least character string A is converted to a string B. Operation of characters are talking about here include: 1. Delete a character 2. Insert a character 3. Will be replaced by one character to another character will be transformed into a string A string of at least B operand used by A to B is called the edit distance is extremely d (A, B). Design an algorithm to calculate any two of the string edit distance.
