Given an input string, reverse the string word by word.For example,Given s = " the sky is blue ",Return " blue is sky the ".Click to show Clarification.Clarification: what constitutes a word? A sequence of non-space characters constitutes a word. could the input string contain leading or trailing spaces? yes. However, your reversed string should not contain leading or trailing spaces. how about multiple spaces between? reduce them to a single space in the reversed string.

pragmatic, the amount of code is not much, but are more code-based. The key is the picture and picture, this is the author most like to see, and sometimes write more, also less than a picture to make it easier to understand, for example, the object instantiation process in this chapter pictures (recommended to study this diagram, enhance stack and heap understanding), the last master to speak very interesting, The content in the interview is often asked.Because just read a chapter, the other co

The JDK (Java Development Kit,java Development Kit, Java Development tool) is a program development environment that writes Java applets and applications. It consists of a running environment on the operating system level, as well as a developer compiling, debugging, and running the tools required for applets and appli

WebService implementation example based on rest mechanism (Java edition) Rest is the abbreviation for the Representational state transfer (general Chinese translation is a descriptive status transfer). 2000 Roy Fielding in his Ph. D. thesis "Architectural Styles and the design of network-based Software architectures" Architecture and web-based Software architecture Design "Rest" is proposed. Rest is an arch

In the middle and late 1990s s, with the rise of the Internet, people strongly hope that the use of applications can be as pleasant as browsing web pages. The traditional C/S structure application requires every userIf a client software is installed on your computer, there is no way to access the application on the server. Therefore, the awkwardness of the C/S structure lies with the simple demand of the masses for daily growth,As a result, it is unable to adapt to the experience of this era and

72. There are several types of streams in Java. The JDK provides some abstract classes for each type of stream for inheritance, say what classes they are respectively. byte streams, stream of characters. The stream of bytes inherits from the InputStream OutputStream, and the character streams inherit from the Inputstreamreader,outputstreamwriter. 75. Describe the principle mechanism of the JVM loading class file? The load of classes in the JVM is impl

distributed lock through Redis, as long as the four conditions in the reliability are guaranteed to be met. Although the internet has brought us convenience, as long as there are problems can Google, but the online answer must be right? In fact, so we should always keep the spirit of questioning, many want more verification. If Redis is a multi-machine deployment in your project, you can try to implement distributed locks using Redisson, which is the official Redis
