Hashtable1. Brief description of the hash table (hashtable)
In. in net work, hashtable is system. A container provided by the collections namespace is used to process and present key-value pairs similar to key/. The key is usually used for quick search, and the key is case sensitive; store the value corresponding to the key. In hashtable, key/key-value pairs are of the object type, so hashtable can support any type of key/key-value pairs.

In the. NET framework, Hashtable is a container provided by the System.Collections namespace for handling and performing key-value pairs that resemble Key/value, where key is often used for quick lookup and key is case-sensitive ; value is used to store the value corresponding to the key. Key/value key value pairs in Hashtable are of type object, so hashtable can support any type of Key/value key-value pairs.

efficiency, the above-mentioned control Library of the respective package level, interface form are different, but the overall requirements of the developer of CSS, JS have a deeper understanding. There are also problems with the reuse, embedding, publishing, and porting of controls.Based on the above considerations, a Canvas-based HT is finally used.

the expiration time of all keys in the database. We call this dictionary an expiration dictionary.The following describes the RedisDb data structure to help you better understand it.3. dictionary is one of the underlying implementations of the Hash type.One of the reasons is that the implementation of the Hash type can be of multiple types. In different scenarios, it can be of different types. However, a Hash key contains many key-value pairs, when some or both key-value pairs are long strings,

In order to achieve a HTML5-based scene games, I use the HT for Web to implement, just 200 lines of code, I can implement the "first person" to operate the forward and backward back and forth, and achieve collision detection.Let's take a look at the effect of the implementation: Http://hightopo.com/guide/guide/core/3d/ht-3d-guide.html#ref_collisionor http://v.youku.com/v_show/id_XMzA5MzUzODc4NA==.html?spm=.

In the more special lots, such as the Big Ravine, point multi-line long, the traffic is inconvenient, the construction organization management difficulty is big, in the traditional construction process, Basic people shuttling back and forth between the work points or telephone communication, inspection, supervision o
Jszip is a javaScript tool that can create, read, and modify. zip files. In a Web application, you need to get resources from a Web server, and if you can merge all of your resources into a single. zip file, you only need to make one request at a time, which reduces the pressure on the server and speeds up the rendering of your Web application. Discuss how the next jszip can be combined with HT applications today. Let's take a look at this Demo:The fi

Implementation of Heman encoding:
1
Build with 2
N-1
Array of units,
Where
N
Units are used to save the initial node,
N-1
Nodes are used to represent Internal nodes.
2
Construct a Heman tree, that is, execute
N-1
Cycle, each time an internal node is generated.
The two nodes with the smallest weight value are their left and right sons.
3
Calculate the Heman encoding of each character.
