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

纪念一下我一晚上写了八遍AC自动机 这是加强版的： cpp include include include include using namespace std; int n, cnt[155], mp[155], len, maxn; char a[155][75], b[1000005]; q 阅读全文

注意：如果是这么个写法，堆数组要开成n+m的。 为什么呢？设想一下从1到2有m条长度递减的路，这岂不是要入队m次…… cpp include include include include using namespace std; struct Edge{ int too, nxt, val; }e 阅读全文
