http://blog.csdn.net/lc_lc2000/article/details/53135839The intention is to make a = b,b a list, the result in the subsequent operation of a, resulting in the value of B also changed, only recall that Python is "reference" this word.To avoid this, there are two ways to avoid this post summary.1. Using the list slice A = b[:]2. Deep copy A = Copy.deepcopy (B)The Python li

Obtains the option value of the drop-down list box, the operation of the list box, and the option of the list box.
Obtain the value in option:
Set the background value to the default value in option.(1)
(2)Var selectlength = $ ("# type option"). length;Alert (selectlength );For (var I = 0; I {Alert ($ ("# type option"). get (I). value );If ($ ("# type option ").
Specific functions to know, in the dropdown box to select a, the left of the list box to display the corresponding value, point that 4 buttons to achieve left and right 2 list box options mutually exclusive, very fun. It is estimated that when we develop, we often need to use it, so we have to post it.
The code is as follows:
var subcat = new Array (); Drop-down list
= "5, 5, 5" /> 25 Style > 26 Style Name = "Btnimg3" Inherit = "Btnimg2" > 27 ATT Name = "Disable" Value = "1" /> 28 Style >
Note: The attribute content of the style supports inheritance, which can reduce the amount of XML and increase the resolution speed;
In addition, the text on the button:
TXT = "str | imgbtn3"
Supports indexing from stringtable. "str |" is a keyword, indicating a problem in the index character l
Introduction:A linked list is one of the important members of a data structure. Because of its simple structure, dynamic insertion, deletion of nodes, the advantages of less time, the list in the development of the application of many scenarios. Second only to arrays (the more simple the wider the application).But. As with its strengths, the drawbacks of the list

List Introduction
A list is a generalization container for a doubly linked list whose data elements can be strung into a logical linear table through a linked list pointer. Unlike vector and deque containers with linear table sequential storage structures, element insertion and deletion in any position in a
This article describes in detail the Python list List array usage in the form of an instance. Share to everyone for your reference. Specifically as follows:
The list in Python is similar to a variable array (ArrayList) in C # for sequential storage structures.Create a list
Copy Code code as follows:

The list is also a basic data structure in our Java, which can be understood as an array structure of arrays of peers, as we know, when we use this set of ArrayList and LinkedList, Always learn the difference between the ArrayList of the underlying array implementation and the LinkedList of the bidirectional list implementation. Here, we are going to speak of a simple one-way
one, the list and array have their own advantages, which is suitable for the use of arrays, what is the appropriate use of linked lists.
When we expect frequent inserts and deletions, the list is more advantageous than the array. However, arrays are more advantageous when we expect random access to be higher than the number of insert and delete operations. Random access is the strength of arrays, because
1. Static linked list
Members of a struct can be of various types of pointer variables, and when a struct has one or more members of the base type that is the type of the struct, the struct is called "reference to its own structure". Such as:
struct link
{
char ch;
struct link *p;
A
P is a pointer member that can point to a struct link type variable. Therefore, A.P = a is a valid expression, and the resulting storage structure is shown i
A doubly linked list is a common data structure. It's not complicated, and it's not too difficult if we're going to make it ourselves. But since the STL has provided us with one, it may be used directly. To do so, not only saves time and effort, but also the reusability of code. Header files and template classes To use a doubly linked list provided by STL, you need to include a header file #include This a
double-ended linked list: A double-ended list is very similar to a traditional linked list. Just a new attribute is added-that is, the reference to the last link node as shown: Because there is a direct reference to the last link. So the double-ended list is more convenient than the traditional linked
First of all, this is a very simple question, Daniel can ignore, novice may encounter, Java in the traversal of a list when deleting the list element throws an exception.This is a simple problem to master seriously insignificant, but novice may be more confused, in which way can be safely and effectively implement Traverse list Delete some of the feature elements
