Problem Description:
Clone an undirected graph. Each node in the graph contains a label and a list of its neighbors. OJ ' s undirected graph serialization:
Nodes is labeled uniquely. We use # as a separator for each node, and, as a separator for node label and each neighbor of the node.
As an example, consider the serialized graph {0,1,2#1,2#2,2}.
The graph has a total of three nodes, and therefore contains three parts as separated by #. First node
The first step: the production of new network card address, start the system.The second step: Modify the hostname (note: Here according to personal needs, do not modify the line, here I am used to build a cluster, modify the hostname to make a distinction) Execute command: Vi/etc/sysconfig/network Modify the value of hostname hostname Step three: Execute command: vi/etc/ Udev/rules.d/70-persistent-net.rules Note: ① comment out the first network card driver Red label Place ② or delete the configu
After cloning is complete, there may be a conflict with the MAC address, go to KVM to remove the eth0 configuration in/etc/udev/rules.d/70-persistent-net.rules, then change eth1 to Eth0, and modify/etc/sysconfig/ Network-script/ifcfg-eth0 Mac, confirm that the MAC address in the two configuration files is the same.Reference:http://blog.51cto.com/freedyong/1361907Modify MAC address after KVM clone is complete under CentOS/vmware copy virtual machine Mo

This article mainly introduces how to use the _ clone () method in PHP programming. the __clone () method is equivalent to a shortest copy, which is the basic knowledge in PHP beginners, you can refer to defining a _ clone () method in the object class to adjust the object cloning behavior. The code for this method will be executed during the Clone operation. In

Turn from: 78793300Prototype modeIn C + +, to copy an object, you can implement a clone function in addition to customizing a copy constructor for object replication. This requires the use of a compiler implementation of a hidden copy constructor, such a practice, more worry.The rationale behind this is the C + + prototype (Prototype) pattern: Specifying the kind of objects created with the prototype instance, and creating new objects by copying them.
Reprint: https://www.cnblogs.com/zouhao/p/7278117.htmlA: In JavaScript, if the cloned object is a basic type, we can assign it directly:1 var sStr = "Kingwell"; 2 var cStr = sstr;3 alert (cStr);//output KINGWELL4 SSTR = "ABC"; 5 alert (CSTR);//output Kingwell;When you assign a value to another variable, the value of that variable is not affected when it is changed.Two: If it's not the basic type, it's all different:1 var aarr = [0,1,2,3];2 var m = aarrr;3 alert (m);//Output 1,2,34 aarr=[3,2,1,0]

Now clone is no longer a new word. With the advent of "Dolly", it is indeed a "fire" for a while. This concept also exists in Java, it allows us to easily create a copy of an object. Let's take a look at how the clone mechanism works in Java?
