Recalling the previous chapter, in the previous chapter we described the Text Processing tool grep command, which is performed by the user according to the specified "pattern" for row matching, the default is greedy mode, the matching results are printed to standard output, and the regular expression is written by a group of special characters, Some of these characters do not represent the original literal meaning, but for the function of control or wildcard, and the regular expression of two ca

Extended KMP AlgorithmWhat is an extension KMP?
The extended KMP is the longest common prefix length for each suffix of the pattern string and the main string.
The extended KMP algorithm is an algorithm that uses the previously known conditions to reduce redundant matches and achieve shorter time.
The purpose of the
After you use extended events to capture the required information in SQL Server, you can choose where you want to store it. For example, in memory or file, but no matter where it exists, it is essentially a large XML. Therefore, reading the XML in SQL Server is the way to parse the extended event results.Microsoft official or some SQL Server forums provide scripts to parse
UWP development entry (10)-extended ListView and uwplistview through inheritance
The reason why this name is used in this article is that the focus is not on custom controls and does not involve the creation of Template and XAML concepts used by CustomControl and UserControl. Instead, an existing class is extended by means of inheritance, and attributes and extended

What is a regular expression?
Describes the features of a text by combining symbols, symbols, and letters and numbers. These characters do not represent the original meaning of the character, but represent control and configuration. The combination of the symbol and letter is called metacharacters.
Why use a regular expression.

whether the values of a [I] and B [J] are equal. If they are equal, ex [I] = J + 1 can be obtained. If they are still not equal, update J to next [J-1] and continue to compare whether a [I] is equal to B [J ...... Until a [I] is equal to B [J] Or until J = 0, a [I] is not equal to B [J]. In this case, ex [I] = 0. Boundary: When ex [0] is obtained, the initial J (used to replace ex [I-1]) is 0.There is another question: how can we find next? Obviously, next is the template String Based on B itse
