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

xml| comparison Two. Comparison of XML and HTMLHTML itself has many drawbacks, for example, content and the layout of the page, presentation form mixed together, excessive expansion. Information stored in the database, after the interpretation and conversion of cgi,asp to HTML format, the original format of the information has become unrecognizable. The gradual popularity of E-commerce, the shortcomings o

The choice of Angular 2 and react is really just a style preference. React is focused on rendering speed and can handle complex UI designs in client or native applications, while angular 2 is more development-wide. It can not only guide us to build our own applications, but also provide some expressive and reusable UI design mechanism.Reactjs Quick Review Reactjs is a set of JavaScript Web libraries built b

After I wrote the first article on Floating Point Number comparison and floating point memory structure There are new ideas for comparing floating point numbers Let's first look at positive numbers.According to the IEEE memory structure, the index is at a high level and the ending number is at a low level.When the memory structure of floating point numbers is compared according to integers, the situation is also true.Therefore, if we compare them her

difference, that is, in a quadrant there are two formulas, there is a total of 8 different situations.The other one is speed:V=f/sinα+cosα, this is easy to deduce, that is to say, F is the speed of interpolation, that is, the speed of moving a pulse equivalent.Obviously, this speed range of 0.707 to 1, the interpolation speed and the actual tool movement speed is not very large, so there is no need for speed adjustment!!It was simple and rude indeed.By the way, the concept of pulse equivalence

This article mainly introduces the comparison between Python 2 and Python 3 and encoding. This article describes in detail. For more information, see the following. I. version comparison The Python version is mainly divided into two categories: Python 2.7.3 is the most widely used Python 2.7.3. Python 3. x, known as Python3: is the latest version, such as Python

By default, the equals (Object O) method of the object (provided by the Base Class Object) is used to compare whether two object variables reference the same object. We must define our own object comparison methods. The icomparable and icompare interfaces are. net Framework. The differences between the two interfaces are as follows: 1. icomparable is implemented in the class of the object to be compared. You can compare this object with another object

Quick sorting (Quick sort)1. Algorithm Description:In the average condition, sort n data to be O (NLG (n)) times compared. In the worst-case scenario, an O (n^2) comparison is required, but this is not a common situation. In fact, fast sequencing is usually significantly faster than other O (NLG (n)) algorithms, because its internal loop (inner Loop) can be implemented efficiently on most architectures, and

Chapter 2 Collection, comparison, and conversion (C # Getting Started classic version 11th ), 1. Set There are some restrictions on data. The most intolerable thing is that once an array is created, the size of the array is fixed and cannot be added. The set contains the functions of the array, and you can add or delete element items at will. There are other functions. The functions of a collection are main

Comparison between Python 2 and Python 3 and python 3 I. version Comparison The Python version is mainly divided into two categories: Python 2.7.3 is the most widely used Python 2.7.3. Python 3. x, known as Python3: is the latest version, such as Python 3.1. In the long run, it is also a future trend. [Differences between Python2 and Python3] 1. From Python2 to P

Comparison Between Layer-2, layer-3, and layer-4 switches (1) layer-2 switches, layer-3 switches, and layer-4 switches: layer-2 switches are relatively mature and belong to data link layer devices, it can identify the MAC address information in the data packet, forward it according to the MAC address, and record the MA

Comparing the two images is similar, this is widely used. At the beginning, I thought this technology was very advanced (of course it was also very advanced) and I had to learn a lot of related knowledge to get started, at least you must have a certain understanding of all aspects before you can do this research. However, opencv provides a set of APIS for this comparison, so that we can easily compare two images. This is the
