AC算法：

#include<iostream>
using namespace std;
int getValue(string n);
void Output(int v);
int main()
{
	string n;
	int value;
	while(cin>>n)
	{
		value=getValue(n);
		Output(value);
	} 
	return 0;
}
int getValue(string n)
{
	int sum,i;
	sum=0;
	for(i=0;i<n.size();i++)
	{
		int temp;
		temp=n[i]-'0';
		sum+=temp;
	}
	return sum;
}
void Output(int v)
{
	string num[10]={"zero","one","two","three","four","five","six","seven","eight","nine"};
	string ret;
	ret="";
	if(v==0)
	{
		ret="zero";
	}
	else
	{
		while(v!=0)
		{
			if(v/10==0)
			{
				ret=num[v%10]+ret;
			}
			else
			{
				ret=" "+num[v%10]+ret;
			}
			v=v/10;
		}	
	}
	cout<<ret<<endl;
