is similar to set. The difference is that set is not automatically ordered, while sorted set can sort members by providing an additional priority (score) parameter, it is insert-ordered, that is, automatic sorting. When you need an ordered and non-repeated list of sets, you can choose sorted set data structure. For example, Twitter's public timeline can be stored as score by posting time, in this way, the query is automatically sorted by time. Implementation Method: In redis sorted set, hashm

1. Comparison between override and new during method overwrite in C # The override keyword in C # is used to overwrite the virtual method and abstract method; In C #, The New Keyword is used to overwrite the "normal" function of the parent class in the derived class (that is, in the context of non-virtual functions and non-Abstract Functions) Below isCodeExample: (for the usage of override, see the section comparing abstract and virtual below)

Performance Comparison of multiprocessing, threading and gevent in python3 ---- process pool, thread pool, and process Pool performance comparison, python3 At present, computer programs generally encounter two types of I/O: Hard Disk I/O and network I/O. I analyzed the process, thread, and coroutine efficiency in python3 for network I/O scenarios. The process uses the multiprocessing. Pool process Pool, the

Speed comparison of opencv image traversal methods and comparison of opencv Images Condition: for a single line, the main frequency is 3.4ghz. the image image.jpg is 768x576. // ReadImage. cpp: defines the entry point of the console application. // # Include "stdafx. h "# include We can see that for image traversal of this size, the pointer method is 30 times faster than the method using the iter

Comparison between C ++ inheritance and Java inheritance, and comparison between java inheritance In C ++, inheritance can be divided into public inheritance (protected) and private inheritance (private ), in Java, there is only one inheritance by default (equivalent to the public inheritance in C ++). Let's look at a piece of code. # Include We have defined A class A, and we can see that: 1. Outside Clas

Comparison of strings in Java and comparison of Java stringsIn C ++, determine whether the values of str_a and str_ B are equal. if (str_a = str_ B) can be used ). However, in Java, if (str_a = str_ B) cannot be used to determine whether the values of str_a and str_ B are equal. "=" Determines whether the storage locations of String str_a and String str_ B are consistent in the memory, rather than whether t

I. Type comparison 1. GetType () method. All classes inherit this method from system. Object. This method can be used together with the typeof () operator to determine the object type. If (myobj.

This article mainly introduces the js time comparison example. The code is simple and you can see the result after running it. For more information, see The Code is as follows:

The Lag and Lead functions can retrieve the data of the first N rows and the value of the last N rows of the same field in a query. This operation can be achieved through table join for the same table, but LAG and LEAD are more efficient. Copy codeThe Code is as follows: create table salaryByMonth ( EmployeeNo varchar2 (20 ), YearMonth varchar2 (6 ), Salary number ); Insert into SALARYBYMONTH (EMPLOYEENO, YEARMONTH, SALARY) Values (1, '20140901', 200805 ); Insert into SALARYBYMONTH (EMPLOYEENO,

Differences between the period-over-period comparison and the period-over-period comparison I have had a lot of discussions on the Internet. After reading it again, my definition is as follows: Year-on-year comparison refers to the comparison of values between the same time points in two adjacent periods. The name

CMP (x, y): Compares 2 objects, which are less than the latter return-1, and equal returns 0, greater than the latter returning 1. Comparison principle of CMP comparison function in Python The CMP functions of Python can be compared between the same type, or between different data types. The comparison size is then determined based on the return value of the Pyth

Comparison of software versions -- Comparison of Java Algorithm Implementation Software Versions Recently, I encountered a small problem in development. The software version is compared: for example, 2.12.3 and 2.2.1. In fact, the Client Version is updated to check whether there are any updates available in the background. The simplest method in Java is to obtain the current Client Version Number and compar

Reconstruction background and causes Recently, due to the continuous expansion of the project team, the Code style in the project varies, and the project may be full of flowers or even anger. Taking into account the survival and development of the team, after many battles, the project team was finally decided to be divided into several teams based on the business to strengthen team management and improve efficiency, while also cultivating tiered talents. For the sake of "Uniform" code style, e

In SQL Server, the software version number is compared to the character string. in SQL, the version numbers such as 1.2.1.571.2.12.57 are compared directly. In this case, a downconversion is required to convert 1.2.1.57 to 00001000020000100057 for comparison. [fun_split_version] is used for comparison. createfunction [dbo].
