首先我们看一下简单的字符串匹配. 你可以把文本字符串s固定,模式字符串p从s对齐的左边缘,作为承担部分完全一致,匹配成功,失败将是模式字符串p整体向右1地点,继续检查对齐部分,重复. #朴素匹配 def naive_match(s, p): m = len(s); n = len(p) for i in range(m-n+1):#起始指针i if s[i:i+n] == p: return True return False 关于kmp算法,讲的最好的当属阮一峰的<字符串匹配的KMP算法>.…
假设主串:a b a b c a b c a c b a b 子串:a b c a c 1.一般匹配算法 逐个字符的比较,匹配过程如下: 第一趟匹配 a b a b c a b c a c b a b a b c 第二趟 a b a b c a b c a c b a b a 第三趟 a b a b c a b c a c b a b a b c a c 第四趟 a b a b c a b c a c b a b a 第五趟 a b a b c a b c a…
