摘要：搞上一棵AC自动机，想让它无限匹配，dfs找环即可 cpp include include include include using namespace std; int n, len; char a[30005]; queue d; bool vis[30005], tmp[30005]; st 阅读全文

摘要：蒟蒻也能写出来的AC代码！这题是AC自动机模板题。插入单词时用一个没出现过的字符隔开就行了。 一些细节请看注释 cpp include include include include using namespace std; char a[1000005], b[1000205];//b数组要开这么 阅读全文
