Introduction
In the computer field, algorithms are an eternal topic. Even if you just put out all the books on algorithm entry, the Chinese and foreign books can even fill the entire Tiananmen Square. But there are still a few of them that are so different. This book is one of them.
This book is a programmer's friend. After many years of work, are the concepts familiar to you, such as quickrank, hackman coding, and KMP, fading into non-connotation nouns in your mind?
This book is a mentor to stu

Given a main string (in the case of s) and a pattern string (substituted by P), we need to find out where p appears in S, which is the pattern matching problem of the string. Knuth-morris-pratt algorithm (KMP) is one of the most common algorithms for solving this problem, and this algorithm is based on Gartner (Donald Ervin Knuth) and Vaughn Pratt conceived in 1974, the same year James · H. Morris also designed the algorithm independently, and eventua

internet connects more and more people each day, another important data center traffic comes from unmanned smart devices deployed in an industrial environment. Two-thirds of the world's economies today rely on the services of network equipment. Gartner expects 25 billion IoT devices to be put into use by 2020, and IDC predicts that the development of the Internet of things will increase the number of smart devices to 30 billion units.Challenge two: B
White Box switch: three methods for network programmability (1)
Even the most demanding IT professional, one word will attract his attention: cost saving. When there is a white box switch in the market-that is, a kind of consumer switch hardware that is pre-installed with a third-party network operating system, network engineers generally hear or understand that this new method may save costs.
However, as the concept of network programmability becomes more and more important, cost saving is not
members of the DG configuration must be configured with a remote logon password file, and each physical standby database must have the latest copy of the password file of the master database. (If you grant or revoke sysdba or sysoper permissions to a user or modify the logon password of a user with these permissions, you must replace the password file with the latest copy of the master database password file on each physical standby or snapshot standby.) configure the master database to accept

But after he enrolled at Case Science University, his passion for music was replaced by an IBM 650 computer. He seems to have a hunch on programming and arithmetic, and this intuition is laid out by a lot of math exercises. Soon, he beca
