1、python从内存角度出发做了限制,递归的大递归深度默认是997/998 可以手动修改python参数来改变该限制 # import sys# sys.setrecursionlimit(max_recursion) 1 2 2、递归的优缺点 递归的缺点 : 占内存 递归的优点: 会让代码变简单 三、初识递归 #需求#A 年龄多大?#A 比 B 大两岁#B 年龄多大?#B 比 C ...
1、何为IP地址: ①IP地址是指互联网协议地址(英语:Internet Protocol Address,又译为网际协议地址),是IP Address的缩写 ②IP地址是IP协议提供的一种统一的地址格式,它为互联网上的每一个网络和每一台主机分配一个逻辑地址,以此来屏蔽物理地址的差异 ③IP地址是一个32位的二进制数,通常被分割为4个“8位二进制...
