If we use C for implementation, it will be a little troublesome. Here we will not talk about complicated mathematical principles, just code.

The equals method in Java is similar to operater = in C ++, that is, how to compare whether two objects have the same content
The clone method in Java is similar to operater = in C ++, but objects in Java are basically referenced semantics and do not have operater = semantics in C ++, therefore, the copy constructor and operater = which are very important in C ++ basically do not exist. In Java, only one object can b

I. arp Communication Protocol processBecause the lan network flow is not carried out by IP address, but by MAC address, the computer recognizes a Machine Based on mac. To send A packet to host B in region A, the local ARP cache table is queried. After the MAC address corresponding to IP address B is found, the data is transmitted. If not, A broadcasts an ARP request packet (carrying the IP address of host B). All hosts on the Internet, including B, receive the ARP request, but only host B recogn

First of all: the scope of JS is different from the scope of other languages, pay special attention.The concept of scope in JS:Represents the area in which a variable or function works, referring to the context in which they are executed, i.e. the context execution environment. There are only two scopes for javascript: global scope and local scope, and local scopes are distinguished by functions.First look at several topics:1.if (true) { var aa= "BB

Driver House [original] by: Shang Fang Wen QPeople who are crazy about downloading Bt and donkey must be familiar with P2P (peer-to-peer) networks. However, while facilitating sharing, the bandwidth usage that comes along with it is also a headache. Therefore, the distributed computing industry association (dcia) proposed the "P4P" network protocol concept, and Verizon's recent experiments also prove that this P2P network upgrade can indeed greatly increase the download speed, and significantly
