socketpair()函数用于创建一对无名的、相互连接的套接子。 如果函数成功,则返回0,创建好的套接字分别是sv[0]和sv[1];否则返回-1,错误码保存于errno中。
the main lessons from last time: not playing a dominated strategy; and putting ourselves into others’ shoes We learn that, when you put yourself in someone else’s shoes, you should consider not only their goals (s_i^{'},s_{-i})\hspace{1cm}for\hspace{0.2cm} some \hspace{0.2cm}s_{-i} Put yourself into other’s shoes A little more about ‘in others’ shoes’ The iterative deletion of dominated strategies Deleting strictly in shoes’argument In the end, Professor helped us distinguish the difference between common knowledge

例如,我们可以定义一个Person结构体类型,它包含两个属性:clothes和shoes: struct Person { var clothes: String var shoes: 简单地说,这意味着您可以通过为结构的两个属性传入初始值来创建结构体,如下所示: let taylor = Person(clothes: "T-shirts", shoes: "sneakers") let : print(taylor.clothes) print(other.shoes) 如果将一个结构指定给另一个结构,Swift会在幕后复制它,以便它是原始结构的完整独立副本。 为了帮助您了解结构体副本的工作原理,请将这段代码放入您的playground: struct Person { var clothes: String var shoes: String ", shoes: "high heels") var taylorCopy = taylor taylorCopy.shoes = "flip flops" print(taylor) print

例如,电子商务用户搜索“dress shoes”,我们定义一个粗略的理想排序: Best-selling dress shoes Low-performing dress shoes Other kinds 这可能与预测亚马逊的股价为123美元相当: Meh pair of dress shoes Best-selling pair of dress shoes Tennis Shoes 正如你看到的搜索, shoes,meh_dress_shoes ... 0,dress shoes,ladies_dress 0,dress shoes,toga_item 正如你所看到的,非常相关的文档比如best_selling_dress_shoes 我们希望f(toga_item,“dress shoes”)得分为0,和f(best_selling_dress_shoes,“dress shoes”)得分为4。 如果dress_shoes比meh_dress_shoes更好,我们可以将该排序标记为“更好”或者“1”。类似地,meh_dress_shoes在dress_shoes之前标记为“更差”或“-1”。

item=shoes&type=women 相反,我们希望访问者能够使用以下更清晰的URL: http://example.com/shoes/women 我们可以通过两种方式之一实现这些结果 - 通过简单的替换或匹配选项 例1A:简单的替换 我们将创建一个重写规则,执行简单的替换,简化长查询URL: RewriteRule ^shoes/women$ results.php? item=shoes&type=women 规则映射shoes/women到results.php?item=shoes&type=women。 item=shoes&type=$1 上面显示的规则匹配shoes/后跟指定类型的URL 。 item=shoes&type=men 此匹配选项允许Apache评估多个模式,而无需为每个模式创建单独的重写规则。 示例1C:匹配字符集 但是,我们还要指定任何项目,而不是仅限制它到/shoes。
