Description: huffman完整源代码C语言实现，有本人超级详细解释（看不懂你去跳楼吧）
算法设计:
1、对给定的n个权值{W1,W2,W3,...,Wi,...,Wn}构成n棵二叉树的初始集合F={T1,T2,T3,...,Ti,...,Tn}，其中每棵二叉树Ti中只有一个权值为Wi的根结点，它的左右子树均为空。（为方便在计算机上实现算法，一般还要求以Ti的权值Wi的升序排列。）
2、在F中选取两棵根结点权值最小的树作为新构造的二叉树的左右子树，新二叉树的根结点的权值为其左右子树的根结点的权值之和。
3、从F中删除这两棵树，并把这棵新的二叉树同样以升序排列加入到集合F中。
4、重复二和三两步，直到集合F中只有一棵二叉树为止。

Description: 打造基于jQuery的高性能TreeView
根据我的项目实践情况，主要是几个关键点：
1：支持静态的树，即一次性将全部数据加载到客户端。*
2：异步树，即一次只加载一级或若干级节点，子节点可以异步加载数据。
3：Checkbox树（可能是静态树也可能是异步树），用于选择（如选择组织机构，选择数据字典项）等，最好是能够支持节点级联（这个是难点）
4：能够承载大数据量，并性能表现优异
5：能够在主流浏览器中运行良好
-TreeView jQuery-based, high-performance build my project based on practical circumstances, mainly a few key points: 1: Support for static trees that once all the data will be loaded to the client.* 2: Asynchronous tree, that is, only load one or more of the first level nodes, child nodes can load data asynchronously. 3: Checkbox tree (the tree may also be asynchronous static tree), used to select (such as the choice organization, select the data dictionary entry), etc., it is better to support node cascade (this is difficult) 4: capable of carrying large the amount of data, and good performance in 5: the ability to run the browser in the mainstream good

Oh, no! - Petya said, walking around his recently bought ground plot. Petya wants to build a new house on it. According to Petya s building project the house should look above like C character.
There are many trees growing on Petya s plot. But everyone who cuts down a tree in Petya s country is sent to cut down trees for the rest of his life. So first of all Petya has to choose a place for building the house without cutting any tree.
He is feeling that he is not able to find the solution on his own, so he decided to ask you to help him.
The task is simplified a little by the fact that Petya s plot has a rectangular shape of size N*M, divided into 1*1 square cells. For each cell it is known whether there are any trees growing there. House can t occupy cells where trees grow.
Fortunately Petya could explain how his house must look above.
