Previous article ([Algorithm Series 20] dictionary tree (Trie)) we introduced the dictionary tree in detail. With these basics, we can better understand the suffix tree.An introduction pattern matching problemGiven a text text[0...n-1], and a pattern string pattern[0...m-1], write a function search (char pattern[], Char text[]), and print out all the positions (n > m) where pattern appears in text.This problem already has two classical algorithms: KMP

DNS Literacy Series 3: Smart DNS (BIND + VIEW) preface: Smart DNS is the function implementation of BIND + VIEW. In China, the first thing we put smart DNS into the market was even (how can we feel unmodest ).

Intelligent DNS is the function realization of bind+view. At home, the first smart DNS into the market is a I (how to give people not humble feeling it).

What is DNS hijacking?DNS hijacking also known as domain name hijacking, refers to the use of certain means to obtain a domain name of the analytic control, modify the resolution of the domain name, resulting in access to the domain name from the original IP address to the modified designated IP, the result is a specific URL can not access or access to the false web site.

Instructions:give you a string with a length of not more than 2000 lowercase letters. Then Q asks Q no more than 10000. Each query asks how many different substrings are in an interval [l,r]. Ideas:If you are counting the number of different substrings of the whole string, the problem is the template. Just follow the method in the paper. The key is to ask how many different substrings are in a range instead of the entire string. But we can't run a suffix
