「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...

However, a preprocessing of the pattern is necessary in order to analyze its structure. The preprocessing phase has a complexity of O(m). Since mless or equaln, the overall complexity of the Knuth-Morris-Pratt algorithm is in O(n). ...
The runtime complexity of this new version in the worst case will be O(N) the size of str.Now we have reached the second part. In this part we will show how to solve an interesting problems using KMP algorithm.The problem asks us to convert a string to a palindrome by appending...
