来自CSDN A_B_C_ABC 网友 KMP字符串模式匹配通俗点说就是一种在一个字符串中定位另一个串的高效算法.简单匹配算法的时间复杂度为O(m*n);KMP匹配算法.可以证明它的时间复杂度为O(m+n).. 一. 简单匹配算法 先来看一个简单匹配算法的函数: int Index_BF ( char S [ ], char T [ ], int pos ) { /* 若串 S 中从第pos(S 的下标0≤pos<StrLength(S))个字符 起存在和串 T 相同的子串,则称匹配成…
Problem Description You are given a number of case-sensitive strings of alphabetic characters, find the largest string X, such that either X, or its inverse can be found as a substring of any of the given strings. Input The first line of the input…

KMP算法实验 1.编程计算模式串(子串)的next值.2.利用KMP算法在主串中找到模式串的位置. 参考代码:---------int getNexlVal( char * s, int j)//求字符串S的j的模式值{ if( j == 1) return 0;//j=1,next[j]=0 int max = 0;//其他情况,next[j]=max+1=1 for( int l = 1; l < j-1 ; l ++ )//从K前面第l个数开始找 { for( int k = 1;…
