题目大意:给你一个串求出来这个串所有的前缀串并且与前缀串相等的数量,比如: ababa 前缀串{"a", "ab", "aba", "abab", "ababa"}: 每个前缀串出现的次数{3, 2, 2, 1, 1},那么结果就是 9.   分析:我们可以用dp[i],表示前i长度的串的结果,那么就可以得到下面的转移方程 dp[i] = dp[next[i]] + 1. 代码如下. ===========…

题意: 求一个字符串的每个前缀在这个字符串中出现次数的加和 解析: 默默的骂一句...傻xkmp..博主心里气愤... 拓展kmp就好多了... 因为拓展kmp每匹配一次   就相当于这些前缀出现了一次 如abcabc abcabc  与 abcabc匹配 为6  这个6就相当于 abcabc  abcab  abca abc ab a各出现了一次 abcabc  与 bcabc 匹配 0 ···· abcabc 与 abc 匹配 为3 相当于abc ab  a 各出现了一次 明白了吧.. km…
