哈夫曼编码与译码

可以实现判断二叉树是否为完全二叉树、判断两棵二叉树是否镜像对称、求一棵二叉树的一个最长枝等功能(Can determine whether the binary tree is complete binary tree to determine whether two binary mirror symmetry, one of the longest seeking a binary tree branches and other functions)

【实例简介】 使用Cadance Allegro手把手带大家一起绘制一块六层板。         设计的PCB板是一个网络相机，选这个设计的原因是涉及面比较广，高速的有DDR、MIPI等，其他RF、电源等等都有涉及，对大家全面了解不同类型的电路设计会比较有帮助。

嵌入式C/C++语言精华文章集锦，关于C/C++语言编程的非常经典的文章。希望能对嵌入式开发人员有所帮助。(Embedded C/C++ language, the article highlights the essence, on the C/C++ programming language is very classic article. Hoping to help embedded developers.)

输入一组数据，xy值，用来拟合椭圆。只要改变输入数据，该代码就可以直接使用。另附上椭圆拟合算法。(Enter a set of data, xy values, used to fit ellipses. Just change input data, the code can be used directly. Attached on the ellipse fitting algorithm.)

1、文本串非空且以文件形式存放，统计匹配的词集非空。文件名和词集均由用户从键盘输入； 2、“单词”定义：由字母构成的字符序列，中间不含空格字符且区分大小写； 3、待统计的“单词”在文本串中不跨行出现，它或者从行首开始，或者前置若干空格字符； 4、在计算机终端输出的结果是：单词，出现的次数，出现的位置所在行的行号，同一行出现两次的只输出一个行号； 5、测试数据：将实验的源程序作为测试文件,从中任意选取“单词”作为测试的词集。 ( 1, a text string not empty and with the file form deposit, statistics matching word set not empty. The file name and word set all by users from keyboard input 2, the "words" definition: from letters constitute sequences of characters, and the space character among excluding case-sensitive Three, to the statistics "words" in the text string not an inter-bank appear, it first started from line or, or lead some space character 4, on a computer terminal of the output result is: the words, in the frequency of, appear in the position of the line number did, with a line of output only twice in a line Numbers 5, test data: will the source program as the test files, to freely choose the "words" as a test of the word set. )
