Test instructions: Known undirected graph, ask to add the least edge to make it a side double connected graph
Idea: It is obvious to indent the point into a tree, add the least side to make the edge of a tree connected
Here is the conclusion: for a tree to add (1+leaf) >>1 strip without the edge can be structured into a double-connected graph, the construction method is obvious (brain repair

The construction code block, static code block and Construction Method in Java are analyzed.
There are three different code blocks: constructing code blocks, static code blocks, and construction methods. What are their differences?
I. Briefly understand how to construct code blocks, static code blocks, and constructor Methods
Class A {// construct the code block
Java static code blocks, construction code blocks, execution order of construction methodsstatic code takes precedence over non-static code because members that are modified by static are members of a class and are executed as the JVM loads the class, while members that are not statically decorated are also called instance members, and need to create objects to be loaded into heap memory. So static will tak
The representation of the destructor method in the inheritance in the PHP construction method, PHP constructs

When a constructor method is not defined in a subclass, the constructor method of the parent class is automatically called. The

Wiring-Anti-interference Solution
In the Integrated Wiring System, steel pipes are used for horizontal cables as much as possible, and bridges are used for laying trunk cables as much as possible. Then, during the construction process, do a Good Job of grounding cross-connection between steel pipes and steel pipes, between steel pipes and bridges, and between bridges and bridges. In such a pipeline, we will lay unshielded cables and large pairs of cab

The construction of the import foundation/* class requires two stages: the first stage: 1. A constructor for the program call subclass 2. Allocates memory for the instance, The memory of the instance is not initialized at this time 3. Specifies that the constructor ensures that all instance store properties defined by the subclass are assigned an initial value of 4. Specifies that the constructor invokes the constructor of the parent class, completing

Azkaban is a workflow scheduling tool. Because of the dependency between tasks, traditional crontab tasks cannot meet the requirements.
Therefore, you need to create a workflow engine. Compared with ooize, Azkaban provides task submission as a client. Ooize randomly distributes tasks to our cluster environment.
Considering the common architecture, we chose Azkaban for workflow engine. However, there will always be various problems in building tutorials on the Internet, which is
