First, we will notice a preprocessing macro at the beginning of TimelineTest. cpp:
#001 # ifdef STRICT
#002 # undef STRICT
#003 # endif
Let's take a look at the STRICT macro. In MSDN, the STRICT macro is used for STRICT type detection. Windows. the h header file defines a series of macros and structures used to make the compiled code run between different Windows versions. When we compile the co
Control please give us a train of thought! ----greedy.
# I used to do a privilege control system, because of the need to modify, and I did not find an effective solution,
# Please give advice, give a general idea, thank you! Requirements are as follows:
# 1. There are multiple children below each father node
# 2. Each child may have a father, and there may be multiple fathers (multiple fathers may differ in rank and

# 3. Each father may manage the same child or a differe

This is a classic problem in Java and is often asked in interviews. In fact, a lot of books or articles have mentioned to Overload hashcode () and Equals () two methods to implement a custom key in the HashMap search, but why and if not to do this will have the consequences, as if very little an article, so write an article to explain.
First of all, if we directly use the following person class as a key to deposit in the HashMap, what will happen?
public class Person {
private String
can add his/her own father (child ?)
The following tree structure can be obtained from the question. The key lies in how to save the tree and how to retrieve it.

Scala classes are similar to Java classes. A simple example is as follows:
class MyClass { var myField : Int = 0; def this(value : Int) = { this(); this.myField = value; } def getMyField() : Int = { return this.myField; } def addToMyField(value : Int) { this.myField += value; }}
If you are curious, you can decompile the compiled code into Java code:
import scala.reflect.ScalaSignature;@ScalaSignature(bytes="\006\00112A!\001\002\001\013\t9Q*_\"mC
