「克努斯-莫里斯-普拉特演算法(Knuth–Morris–Pratt algorithm / KMP algorithm)」是一種字串搜尋演算法(string-searching algorithm),可用來在一長串文字中,尋找特定字串。 匹配陣列(PS Array) 用來比較一字串中的內容重複出現的程度;在比較兩字串時,若兩字串不相符,匹配陣列(PS Array)可協助將比較的字串往後移。
This article uses a two-dimensional dp array (but the space complexity is still O (M)) to redefine the meaning of the elements, which greatly reduces the code length and greatly improves the interpretability。 PS: The code of this article refers to "Algorithm 4". The name ...

KMP算法全称是Knuth-Morris-Pratt Algorithm(克努特—莫里斯—普拉特算法)实际上就是优化后的模式匹配算法。这个算法是由D.E.Knuth、J.H.Morris、V.R.Pratt这三位大佬提出。 Donald·E·Knuth大佬帅照附上 James H. Morris大佬帅照附上 Vaughan·R·Pratt大佬帅照附上 ...

KMP Algorithm Resource for Beginners By codechef123, history, 2 years ago, KMP pattern searching is an advanced algorithm & it is hard to explain it in simple terms. I stumbled on to this resource recently. I think it is a good starting point for people wanting to understand the basic...
A fast string searching algorithm[J]. Communications of the ACM,1977,10: 762-772. 之前我们刚开始说坏字符的时候,是不是有可能会出现负值的情况,即往左移动的情况,所以我们为了解决这个问题,我们可以分别计算好后缀和坏字符往后滑动的位数(好后缀不为 0 的情况),然后取两个数中最大的,作为模式串往后滑动...
