前面的开门部分: 挂载点在Linux就是目录,在Windows里面是 C D E之类的盘符。 分配盘符的过程就是挂载。 找到设备,分配设备文件名,然后分配挂载点也就是目录,然后连接起来。这就是挂载。 设备文件名都是默认的。 先创建目录,也就是挂载点,但现在的默认挂载点以及都默认创建好了,在  /mnt目录下: 然后: 这个iso9660其实是可以省略的,因为默认了,这个是文件格式。 ISO 9660 文件系统是一个标准CD-ROM文件系统。 用完后要卸载,但是卸载的时候要用命令,直接摁光驱是不会弹出的。 并且,要退出挂载目录再执行命令。 只加这一个目录就可以了。 ----------------------------------------------------------------------------------------------------------- 正式部分: Linux的挂载,每个设备都有一个设备名就如同window里面的设备也有个设备名如cdef盘,一样,只不过windows是自动分配的, Linux是需要手动吧设备名跟目录结合到一起的。 Linux里面的盘符就是目录。所有盘符跟设备名的挂载就是设备名与目录的挂载。 写了一个脚本文件,然后把他所在的目录用mount命令改变成非可执行, 二、用mount命令挂载U盘和光盘 硬盘系统会自己挂载

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: Basically I'm trying to dispatch a custom made mouse click event to a text input element using the following code (see this jsFiddle ): function simulateClick(id) { var clickEvent = document.createEvent("MouseEvents"); clickEvent.initMouseEvent("click", true, true, window, 1, 0, 0, 0, 0, false, false, false, false, 0, null); var element = document.getElementById(id); element.dispatchEvent(clickEvent); } When I run that code on a type="checkbox" element it works perfectly fine but it doesn't work at all when called on a type="text" element.

【Leetcode 913】【Hard】Cat and Mouse 博弈论

描述 913. Cat and Mouse Hard A game on an undirected graph is played by two players, Mouse and Cat, who alternate turns. The graph is given as follows: graph[a] is a list of all nodes b such that ab is an edge of the graph. Mouse starts at node 1 and goes first, Cat starts at node 2 and goes second, and there is a Hole at node 0. During each player's turn, they must travel along one edge of the graph that meets where they are. For example, if the Mouse is at node 1 , it must travel to any node in graph[1] . Additionally, it is not allowed for the Cat to travel to the Hole (node 0.) Then, the
