rt，以下代码：

#include<bits/stdc++.h>
using namespace std;
string rand_str(int len){
	string s="floirr",s1; 
	for(int i=1;i<=len;i++){
		s1+=s[rand()%5];
	} 
	return s1;
}
int main(){
	freopen("1.in","w",stdout);
	srand(time(0));
	int n=rand()%1000,l=rand()%10000,r=rand()%10000;
	cout<<n<<' '<<l<<' '<<r<<endl;
	for(int i=1;i<=n;i++){
		cout<<rand_str(rand()%15)<<endl;
	} 
	return 0;
}
