注意：每次需要更新s值。

#include<iostream>
#include<cstdio>
#include<cmath>
using namespace std;
int main()
    double c;
    int i=0;
    while(cin>>c)
        double s=0.0;
        if(c==0)
            break;
        for(i=2;;i++)
            s+=(1.0/i);
            if(s>=c)
                cout<<i-1<<" card(s)"<<endl;
                break;
            
        
    
    return 0;
