题意:给你两个字符串p和s,求出p在s中出现的次数. 显然,我们要先把模式串放到前面,之后主串放后面,中间隔开,这样就可以根据前缀数组的性质来求了. 我先想直接把p接到s前面,之后求Next数组对strlen(p)取余==0的就可以,之后WA.最后发现A AASSAAS的时候有bug,只有又想到在p和s中间加个不可能出现的字符'$'就可以了,戒指就A了. #include <bits/stdc++.h> using namespace std; const int INF=0x3f3f3f3f…

Hash,一般翻译做散列.杂凑,或音译为哈希,就是把任意长度的输入(又叫做预映射, pre-image),通过散列算法,变换成固定长度的输出,该输出就是散列值.这种转换是一种压缩映射,也就是,散列值的空间通常远小于输入的空间,不同的输入可能会散列成相同的输出,而不可能从散列值来唯一的确定输入值.简单的说就是一种将任意长度的消息压缩到某一固定长度的消息摘要的函数. 这里就只介绍一种Hash函数,其实有好多种,但是目前只学了这一种. 题目链接:http://acm.hdu.edu.cn/showpr…
