从理论上讲,蛮力算法之多迭代n - m + 1轮,且各轮至多需进行m次比对,故总共只需做不超过(n - m + 1) * m次比对。因为m << n,渐进的时间复杂度为O(n * m)。 2 KMP算法 2.1 构思 蛮力算法在最坏情况下所需时间,为文本串长度与模式串长度的乘积,故无法应用于规模稍大的应用环境,很有必要改进。

The preceding example shows the same algorithm, but uses string values instead of an enum. You would use this scenario if your application responds to text commands instead of a regular data format. Starting with C# 11, you can also use aSpan<char>or aReadOnlySpan<char>to test for constant...
For the example of how to use those patterns to build a data-driven algorithm, see Tutorial: Use pattern matching to build type-driven and data-driven algorithms.Declaration and type patternsYou use declaration and type patterns to check if the run-time type of an expression is compatible ...

A string pattern-matching algorithm uses a character string, pattern, to search another character string, text, for the first or all occurrence(s) of the pattern in the text. This article presents a string patternmatching algorithm using a mapping table and an automaton. The number of states ...
This paper proposes a Pattern Matching Algorithm Using Changing Consecutive Characters (PMCCC) to make the searching pro- cess of the algorithm faster. PMCCC enhances the shift process that determines how the pattern moves in case of the occurrence of the mismatch between the pattern and the ...
In this paper we consider the problem of secure pattern matching that allows single character wildcards and substring matching in the malicious (stand-alone) setting. Our protocol, called 5PM, is executed between two parties: Server, holding a text of le
