@[Jelly_Goat](/space/show?uid=122927) 给你个板子
```cpp
template<int set_,int mod>
struct trie{
struct node{
node* son[set_];
int flag;
};
node* root,*ctrl_c;//复制一下后面迭代查找有用
inline void init(){
clear(ctrl_c);
root=new node(),ctrl_c=root;
}
inline void insert(string line){
root=ctrl_c;
for(int i=0;i<line.length();i++){
if(root->son[line[i]%mod]==NULL){
root->son[line[i]%mod]=new node(),root->son[line[i]%mod]->flag=0;
}
root=root->son[line[i]%mod];
}
root->flag++,root=ctrl_c;
}
inline int count(string line){
root=ctrl_c;
for(int i=0;i<line.length();i++){
if(root->son[line[i]%mod]==NULL){
root=ctrl_c;
return 0;
}
root=root->son[line[i]%mod];
}
return root->flag;
}
inline void del(string line){
