#include <vector>
#include <string.h>
#include <iostream>
using namespace std;

 int main()
{
    int sum=0,j=0;
    char n[101];
    char a[11][6]={"zero","one","two","three","four","five","six","seven","eight","nine"};
    vector <int> r;
    cin>>n;
    for(int i=0;i<strlen(n);i++)
        sum+=n[i]-'0';
    do
    {
        r.push_back(sum%10);
        j++;
        sum/=10;
    }while(sum!=0);
    cout<<a[r.back()];
    r.pop_back();
    while(!r.empty())
    {
        cout<<" "<<a[r.back()];
        r.pop_back();
    }
    
    return 0;
}

vector真好用啊
