The idea is plain and efficient, but time complexity is O (MN), and M and N are the lengths of strings and pattern strings, respectively. Pattern matching is a common application problem, with a wide range of people thinking to optimize. Rabin-karp algorithm, fi

To discuss the technology related to blog, it is necessary to talk about RSS, the abbreviation in English can have several sources, and by different technical groups do different interpretations. It can be either "Rich Site Summary" or "RDF site Summary" or "Really Simple Syndication". Why do you have so many meanings? This is also from the RSS section of the relationship today is not clear.

Using the like ' [^s][^y][^s]% ' mode does not necessarily have the same name every time you find it. It is possible to get only 14 names (instead of 19), except for system table names, all names starting with s or the second letter Y or the third letter s are eliminated from the result. This is because matching a stri

The most important step:
You have to see the mistake with your own eyes, or you will be wrong in the wrong direction because of misinformation or other errors.
Or get the wrong firsthand information is very important.
