codeforces535D:Tavas and Nafas

Today Tavas got his test result as an integer score and he wants to share it with his girlfriend, Nafas.

His phone operating system is Tavdroid, and its keyboard doesn't have any digits! He wants to share his score with Nafas via text, so he has no choice but to send this number using words.

He ate coffee mix without water again, so right now he's really messed up and can't think.

Your task is to help him by telling him what to type.

Input

The first and only line of input contains an integer s (0 ≤ s ≤ 99), Tavas's score.

Output

In the first and only line of output, print a single string consisting only from English lowercase letters and hyphens ('-'). Do not use spaces.

Sample test(s)

题意简单，就是每输入一个阿拉伯数字（0~99），输出它对应的英文单词。

代码如下：

#include

using namespace std;
char a[15][10]={"zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten"};
char b[15][10]={"eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen"};
char c[15][10]={"twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety"};
int main()
{
	int n;
	while(~scanf("%d", &n))
	{
		if(n>=0 && n<=10) printf("%s\n", a[n]);
		else if(n>=11 && n<=19) printf("%s\n", b[n-11]);
		else
		{
			if( (n%10) == 0) printf("%s\n", c[(n-20)/10]);
			else
			{
				printf("%s-%s\n", c[n/10-2], a[n%10]);
			}
		}
	}
	return 0;
