Jumping game
Given a non negative integer array, you are initially located in the first position of the array.
Each element in the array represents the maximum length you can jump at that location.
Determine whether you can reach the last position.
Example 1:
Input: [2,3,1,1,4]Output: trueExplanation: jump 1 steps from position 0 to 1, then jump 3 steps to the last position.
Example 2: input: [3,2,1,0,4]
Output: falseExplanation: anyway, you always get to the index 3. But the maximum jump length is 0, so you can never get to the last position.Train of thought: adoptdynamic program...
// getters
const getters = {
netStatusMonitorData: state => {
return state.faultInfo;
},
};
const mutations = {
[baseTypes.UPDATE_DATA_MODULE](state) {
//oldcode
//state.faultInfo =pageData.dataSource;
//After the assignment does not trigger the getter method to refresh, it changes the deep copy to trigger the getter refresh.
let tempData = {};
$.extend(true, tempData, pageData.dataSource);
state.faultInfo = tempData;
}
};
1、Clicking rate
The ratio between the number of hits and the number of keywords displayed.
2、The matching degree of creative content and keywords refers to whether the key is smooth after the key is incorporated.
For example:
Key words: English Schools
Originality: to learn English well {Harbin English school}.
3、Correlation between creative content and keywords
4、Landing page: correlation between keywords, creativity and landing pages
5、Click performance: netizens click on search results and enter the website after...

ldd
Function: Used to view shared libraries needed by a program to run, often used to solve problems that a program cannot run because it lacks a library file.
Example: look at the library that test programs run on:
/opt/app/todeav1/test$ldd test
libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00000039a7e00000)
libm.so.6 => /lib64/libm.so.6 (0x0000003996400000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00000039a5600000)
libc.so.6 => /lib64/libc.so.6 (0x0000003995800000)

In ACC_DOCUMENT-CHANGE
LOOP AT c_accit ASSIGNING <wa_accit> WHERE rebzg eq 'V'.
<wa_accit>-rebzg = ''.
ENDLOOP.
Then you can see Invoice Ref. in FBL1N is the Document No.
So far, we have talked about the collection of high-level data types belonging to containers for single elements. They either store elements in succession or store them as interdependent pointers, each representing an independent value that belongs to a particular type.
The dictionary we’re going to talk about today is different. It stores not a collection of single values, but a collection of key-value pairs.
What is the key value pair? It is a word literally translated from English key-value pair. As the name implies, a key pair represents a pair of keys and values.
Note that...
IOCSingleton mode –Bean
SpringThe bean in China is determined by scope.
scopeThere are 4 types:
1.singleton：The singleton model indicates that the object obtained through the Spring container is unique.Commonly used and defaults.
2.prototype：Multiple-instance model, which means that objects retrieved through the Spring container are different (similar to the unique object address of new in Java infrastructure).
3.reqeust：The request indicates that it is valid in a HTTP request.
4.session：Session, which is valid in a user session.
1.Create an object
public class User {

Problem description
In the city of N, the location of n city is just the vertex, just forming a positive n shape. In order to promote the development of trade, it is necessary to open several canals (the number of canals can be 0) between certain cities. The canals must be opened in a straight line, starting and ending in two different cities.It means that the two canals cannot intersect (the two canals share a city as the starting and ending point), otherwise, there will be war between the cities because of the cost of water used in the canal. The number of schemes for opening the canal.
Inp...
