本学期开始做真正意义上的研究，主要方向为wireless and mobile network，VANET。之前一直在看paper，现在由于任务需求，需
Sort List
2014.1.14 23:17
Sort a linked list in O(n log n) time using constant space complexity.
Solution:
The first thing I thought of about this problem is merge sort. It's weak
Insertion Sort List
2014.1.14 21:58
Sort a linked list using insertion sort.
Solution:
Everyone must've have learned about insertion sort on some data structure textbooks, like "Data Struct
Binary Tree Preorder Traversal

Given a binary tree, return the preorder traversal of its nodes' values.
For example:Given binary tree {1,#,2,3},
1

Given a binary tree, return the postorder traversal of its nodes' values.
For example:Given binary tree {1,#,2,3},

本篇文章重点说明什么是函数柯里化，这个语法现象的背后动机是什么，有什么样的应用场景，以及与部分应用函数(Partial Applied Function)之间的联系 1. 什么是柯里化函数
A way to write functions with multiple parameter lists. For instance
def f(x: Int)(y: Int) is a
ApplicationContext能读取多个Bean定义文件，方法是：
ApplicationContext appContext = new ClassPathXmlApplicationContext（
new String[]｛“bean-config1.xml”，“bean-config2.xml”，“bean-config3.xml”，“bean-config4.xml

但是用java来实现有一个问题。
由于Java无法像C那样“传递参数的地址，函数返回时能得到参数的值”，唯有新建一个辅助类：AuxClass
import ljn.help.*;
public class BalancedBTree {
BeanUtils.copyProperties VS PropertyUtils.copyProperties
作为两个bean属性copy的工具类，他们被广泛使用，同时也很容易误用，给人造成困然；比如：昨天发现同事在使用BeanUtils.copyProperties copy有integer类型属性的bean时，没有考虑到会将null转换为0，而后面的业
