#include<cstring>
#include<queue>
#include<cmath>
#include<set>
#include<sstream>
#define ll long long
using namespace std;
const int N=105,INF=0x3f3f3f3f;
string tra[12]={"zero","one","two","three","four","five","six","seven","eight","nine"};
int main(){
    string s,s1;
    ios::sync_with_stdio(false);
    cin>>s;
    int ans=0;
    for(int i=0;i<s.length();i++){
        ans+=(s[i]-'0');
    }
    stringstream ss;
    ss<<ans;
    ss>>s1;
    cout<<tra[s1[0]-'0'];
    for(int i=1;i<s1.length();i++){
        cout<<" "<<tra[s1[i]-'0'];
    }
    cout<<endl;
}
