Do I need to implement KMP Algorithm in a real interview? Not necessary. When you meet this problem in a real interview, the interviewer may just want to test your basic implementation ability. But make sure you confirm with the interviewer first. 在面试中我是否需要实现KMP算法? 不需要,当这...

KMP algorithm, and theBoyer-Moore algorithm. Since these algorithms are usually studied in advanced algorithms class, for an interview it is sufficient to solve it using the most direct method — Thebrute force method.

KMP算法针对子串计算$next$数组,主串指针不会回退。记主串为$T[0\cdots n-1]$,子串为$P[0\cdots m-1]$。假设主串和子串分别在第$i$和$j$个位置失配($T[i]\ne P[j]$),那么有$P[0\cdots j-1]=T[i-j\cdots i-1]$,假设下一步主串应该与子串第$k$个字符继续比较(注意主串$i$指针不...
[Leetcode][python]ImplementstrStr()/KMP算法 题目大意字符串匹配解题思路两种思路: 1. 直接一个个匹配过去(遍历) 2. KMP算法:参考 http://www.ruanyifeng.com/blog/2013/05/Knuth%E2%80%93Morris%E2%80%93Pratt_algorithm.html http://blog.csdn.net/coder_orz/article/details/5170... ...
But this way is a brute-force algorithm, too. may be this question want you to use brute-force. The high effective algorithm is to use KMP algorithm. classSolution{public:intstrStr(string haystack,string needle){intm=haystack.length(),n=needle.length();if(!n){return0;}vector<int>lps=...

KMP using DFA: 先根据needle构建一个DFA,然后从haystack的第一个字母开始向后找,找到第一个occurrence或者遍历完haystack则循环结束。R代表alphabet字母表,或者Radix,既needle中distinct char的数量,对ASC II码我们可以简单假设为256。假如needle是Unicode则我们需要使用improved KMP,或者其他方法比如Boyer-Moore。 对于Mul...
