number of keywords recorded is small and can be decomposed, the base sorting is better. Although bucket sorting has no requirement on the structure of keywords, the average time can reach the linear order only when the keywords are randomly distributed. Otherwise, the bucket sorting is the square order. At the same time, note that the box, bucket, and base allocation sorting assume that if the keyword is a number, the value is non-negative. Otherwise, map it to the box (bucket) to add the corre

1. The technical direction is constantly changing. You may have just mastered struts, but struts 2, Spring, and grails have come out again; just mastered the essence of jquery, but found that HTML5 and css3 are available, which is redundant in most cases; just understood the concepts of thread pool and so on, a single-thread framework suddenly became popular; just learned MySQL, MongoDB went viral again. Basically, many new things will come out every year in most technical directions. If yo

Online programming website

It provides compiling and Running Environments in various languages, which greatly simplifies the installation and configuration complexity of client programs and achieves real-time programming;
Of course, if you want to use the computing resources of these machines, it is also a good way.
Supported languages include:
Ada (Gnat)
Algol-68

Intel will release some Linux programming tools on Thursday to enable Linux programs to run better on the microprocessor it produces. The following is a detailed description of these tools.
1. editing tool for Linux programming tools: you no longer have an integrated environment for programming in Linux. You can use a tool similar to EDIT-the classic vi to EDIT the source program. Of course, there are more advanced ones, such as joe and emacs. In short, the editing program and compilation work a

There are not many advertisements, and there are only a variety of advertising platforms, sdks, and chaos.
The rest will be discussed later ....

because the results are sorted. However, in general, sets are unordered, and the result we get may be any sequence. Redis also supports sorting sets. Each item corresponds to a score and then sorts sets Based on this score.
SummaryRedis is a multi-functional database with rich advanced features. It also has a relatively new Product accessory to expand its capabilities so that it can handle use cases that cannot be processed only on one machine. Take some time to learn and use it in your system.
object (some may say it is at the lowest level), because the service definition is mapped to a process-oriented language, for example, COBOL, PL/I, or message queuing systems, such as JMS or MSMQ, except for Object-Oriented systems.

Access programmers set out without any experience in hunting elephants. They wore gorgeous hunting costumes, carried all the equipment, found elephants with beautiful telescopes, and found that they forgot to trigger the trigger.
Visual access programmers Mount bullets, raise rifles, and aim at elephants. This makes it ridiculous to see who has escaped. They cannot catch elephants because they have a preference for multiple controls and their jeeps have too many steering wheels to drive.

Introduction to GCC
1. GCC is the abbreviation of GNU Compiler Collection. Originally, it was a C language compiler (gnu c compiler). The author was Richard Stallman and was the founder of the GNU project. Now it supports multiple languages, such as C, C ++, Java, Pascal, Ada, and Cobol.
2. Main features:
GCC is a portable compiler that supports multiple hardware platforms and even provides comprehensive support for uncommon computers such as
