python2中汉字乱码问题

#python2中汉字乱码问题

###1、写的代码模块需要指定编码 如果代码没有指定coding,python就默认所有的字符为ASCII码, ASCII码只支持256个字符,ASCII码不支持中文,所以就报错。 所以要在代码前写上#coding:utf-8或#coding:gbk 但通用写上#coding:utf-8

###2、python2内部所有编码统一为unicode unicode可以处理世界上所有语言的字符。

用装饰器实现缓存机制，避免斐波那契数列递归实现中的重复调用，然后比较存在缓存和没有缓存下的运行时间。

一行 Python 实现树

一行 Python 实现树

使用 Python 内置的 defaultdict，我们可以很容易的定义一个树形数据结构：

def tree(): return defaultdict(tree)

就是这样！

re-imagined / 双绞线连计算机.md
Last active April 5, 2016 05:00

将两计算机通过双绞线直接连接就是一端是586A，一端是586B。

  • 568A标准：绿白，绿，橙白，蓝，蓝白，橙，棕白，棕
  • 568B标准：橙白，橙，绿白，蓝，蓝白，绿，棕白，棕
  • 568A和568B的标准就是把 1 和3，2 和6 的顺序换过来了，其他不变。
两台电脑直联,一头接568A,一头接568B，8根线中4，5，7，8不用,只有橙白1，橙2，绿白3，绿6四根线传数据。
1，2发数据,3，6接收数据，所以必须1，3相接，2，6相接，才能实现一头发数据，一头接收数据。

机器的位数与数据类型的关系

32位编译器：

  • 32位系统下指针占用4字节
      char ：1个字节
      char*（即指针变量）: 4个字节（32位的寻址空间是2^32, 即32个bit，也就是4个字节。同理64位编译器）
      short int : 2个字节
      int：  4个字节
      unsigned int : 4个字节
 float: 4个字节

GrayCode_Generator

这里使用两种方法来生成格雷码

######第一种是生成二进制的字符串

vector<string> GrayCode(int n)
{
    int x = pow(2, n);//n位格雷码有 x = 2^n 个
    vector<string> graycode;//用字符串来存格雷码

    if(n == 0)

用char 来声明字符串时，最后会接一个结束符，长度比字符数大一 
char STR[] = "Hello\!";

有六个字符，但

cout << sizeof(STR);

的结果是7，因为后面还有一个结束符 "\0"。

for(int i = 0 ; i&lt;=6; i++){
