Input

There are multiple sets of data, each set is a row, and each set is a small article. Each small article is composed of lowercase letters and spaces, no punctuation marks, and the end of input when # is encountered.

 

Output

Each group outputs only one integer, on its own line, that represents the total number of distinct words in an article.

 

Sample Input

you are my friend #

 

Sample Output

#include <iostream>  
#include <sstream>  
#include <string>  
#include <set>  
using namespace std;  
set<string> t;  
intmain()  
{  
    string  s,row;  
    while(getline(cin,row)&& row!="#") //按行输入  
    {  
        t.clear();     
        stringstream str;  
        str<<row; //Type conversion  
        while(str>>s) //>>Each input ends with a space or '\0' and stops when a space is encountered  
        t.insert(s); //insert  
        cout<<t.size()<<endl; //return the number of different values  
    }  
    return 0;  
}
