WebNov 7, 2024 · KMP (Knuth Morris Pratt) Algorithm: The idea is whenever a mismatch is detected, we already know some of the characters in the text of the next window. So, we take advantage of this information to avoid matching … Web我周围的人告诉我，对于短字符串来说，KMP已经足够好了，但是如果您需要性能，并且打算使用大字符串，那么这不是一个好的选择。但是他没有告诉我细节. 因此，以下是我的问题： 为什么不在 String.indexOf（）中使用KMP呢; 为什么KMP不是一个大字符串的好选择

Web字符串匹配算法_朴素字符串匹配算法. 查找模式字符串在文本中的所有出现是文本编辑软件经常要面对的一个问题。一般而言文本就是要编辑的文档,而模式字符串往往由用户来指定,高效的字符串匹配 算法可以提高程序的响应性能,当然字符串匹配算法的应用远远不止于此,例如在生物计算科学中查找 ... WebFeb 20, 2024 · The original KMP Algorithm has the runtime complexity of O (M + N) and auxiliary space O (M), where N is the size of the input text and M is the size of the pattern. Preprocessing step costs O (M) time. It is hard to achieve runtime complexity better than that but we are still able to eliminate some inefficient shifts. In computer science, the Knuth–Morris–Pratt string-searching algorithm (or KMP algorithm) searches for occurrences of a "word" W within a main "text string" S by employing the observation that when a mismatch occurs, the word itself embodies sufficient information to determine where the next match could … See more A string-matching algorithm wants to find the starting index m in string S[] that matches the search word W[]. The most straightforward algorithm, known as the "Brute-force" or "Naive" algorithm, is to look … See more Since the two portions of the algorithm have, respectively, complexities of O(k) and O(n), the complexity of the overall algorithm is O(n + k).
