character is positive or negative, not the words or only the sign to run abnormal, and then began to traverse Ah, transformation ah. The focus is on the transformation. We can use switch for common conversions. But the source is not yo. For 128 to 127 is the cache good number, in addition to do a stirng to int conversion, in this int conversion to the char directly into int and then to the operation of Unicode, this is dug too deep, we do not need to delve into, Do some swtich conversion.The co

The javascript Implementation Framework highly changes with the content, and the javascript implementation framework
This example describes how to change the height of the javascript framework with the content. Share it with you for your reference. The details are as follows:
There are two methods:
1. changed through the parent page
Here, we need to understand that the two attributes of the framework, c
Beautils tool class implementation principle, beautils tool class implementationFor more information about the introspection and reflection mechanisms, see this blog [not finished yet, in the draft ].
Let's talk about bean attributes. bean attributes refer to the names after the get/set method, rather than the attributes of the class:
For example:
Private String username; // The bean attribute does not refer to the public String getUsername () {//,
Python implementation of decision tree and python implementation of decision treeAdvantages and disadvantages of Decision Tree algorithms:
Advantages: low computing complexity, easy to understand output results, insensitive to missing median values, and the ability to process irrelevant feature data
Disadvantage: the problem of over-matching may occur.
Applicable data types: numeric and nominal

I have also done an encyclopedia before, and it also involves the classification function, but it is not an infinitely level classification, however, it seems difficult to implement such a function in a simple way. I have also done an encyclopedia before, and it also involves the classification function, but i

Vpn Principle and Implementation-tunnel implementation theoretically reasonable ip over ssl needs some additional technical support before it can be used, you must try to re-encapsulate an ip data packet by ssl. This action cannot be performed in the original standard protocol stack. The standard protocol stack does not support two-way data flow, one of the solutions is to modify the Protocol Stack and impl
Simple implementation of AJAX paging effect and ajax paging implementation
Recently, I wrote a function to add a role to a user group, requiring that one side be an unadded role, the other be an added role, and the search function. Click Add to save the operation by using ajax.
The function is to be queried by page. There are 2x2 and 4 ajax entries in the lower part of the page...

Simply select the C ++ Implementation of sorting and select sorting implementation
Simple selection and sorting use the simplest selection method, that is, the minimum (or maximum) keyword is selected in the residual sequence, and the position is exchanged with the first keyword of the residual sequence, until the entire sequence is ordered.
Directly run the Code:

Thoughts:First, the entire sequence of records to be sorted is divided into several sub-sequences for direct insertion sorting. When the records in the whole sequence are "basic order", all the records are directly inserted for sorting.
Note:
(1) The subsequence is not simply "segmented by segments", but a subsequence o
