Problem Description: 0-1 Backpack: There are n items and a backpack with a weight of M. (Each item is only one) the weight of item I is w[i], value is p[i]. Solving which items are loaded into the backpack can make the sum of the greatest value. Dynamic planning: Dynamic programming algorithms are often used to solve problems with some of the best properties. There may be many possible solutions to such problems. Each solution corresponds to a value,

One, two main problems in network programming One is how to accurately locate the network on one or more hosts, and the other is to find the host after the reliable and efficient data transmission.In the TCP/IP protocol, the IP layer is mainly responsible for the location of the network host, the routing of Data transmission, the IP address can uniquely determine a host on the Internet.The TCP layer provides reliable or unreliable data transmission me

Introduction: The difference between procedural programming and object-oriented programming is not whether to use functions or classes. that is to say, procedural programming may be used for classes or objects, only functions are used, and object-oriented programming is also possible. So where are their differences? Pr

This series of articles will give a comprehensive introduction to parallel programming technology (also called multi-core programming technology) and applications in. net4. The topics in this article are as follows: 1. Differences between parallel programming and multi-threaded programming. 2. Advantages and Disadvanta

Socket is a way of inter-process communication, and other processes of communication between the main difference is: to achieve inter-process communication between different hosts, the network of a variety of services are based on the socket to complete the communication, to solve the network of two host communication problems, the first to uniquely identify the process, In TCP/IP network protocol, it is through (IP address, protocol, port number) ternary group to identify the process, solve the

Feeling for the work of programming, I started to think so, or we are now good. For example, the language developed, developed into easier to understand and programming, tools also developed, programming time is more convenient, such as the current smart tips. But it seems a bit one-sided, and it's hard to really understand the history of a technology without und

Socket Basic Concepts: Sockets are the cornerstone of communication, and are the basic operating unit of network communication that supports TCP/IP protocol. Sockets can be viewed as endpoints of two-way communication between different host processes, which form the programming interface between a single host and the entire network. Sockets exist in the communication domain, which is an abstract concept that is introduced in order to handle a generic

Talking about how to improve the programming efficiency. 1. Improve working experience Experience comes from practice. Read a few skills books and excellent articles from various websites at ordinary times. If a book is a step, then there will be tens of thousands of steps in the life of people waiting for me to cross. Every step will be immeasurable wealth, and the next step, will take me into a new realm, access to new knowledge. See Learn to do.

encodings to debug or track the execution of a program. I find that the debugger is good at giving information. But we're not here to talk about the value of your debugger. Of course, there are reasonable reasons to want to produce some text-tracking information for your program. In Eclipse's current set of AspectJ Development Tools (AJDT), there is a good example of an aspect that implements the process of tracking a program. In Eclipse's help, there is a detailed description of this example.

Pick up an articleAn understanding of object-oriented programming?A: Object-oriented programming is to abstract your requirements into an object and then analyze its characteristics (attributes) and actions (methods) against this object. This object we call class. One of the features of object-oriented programming is encapsulation, which is to put the function yo

Accustomed to C + + Programming Mode: Edit, save, compile, run and debug after, forget there is actually another programming mode-interactive programming. Many scripting languages provide similar consoles, enter script statements directly, and perform a carriage return, and the results are immediately displayed without having to undergo a complex save and compile

First, introduce TCP: (Transmission Control Protocol Transmission Control Protocol) is a connection-oriented, reliable, byte-throttling based Transport layer communication protocol. In contrast, UDP is an open, connectionless, unreliable Transport layer communication protocol. below, I do the client and server-side QT implementation at once. My development environment is: QT Creator 5.7. First look at the effect of the picture: One: Client-side programming
