Given a non-negative integer N, your task is to compute the sum of all the digits of N, and output every digit of the sum in English.

Input Specification:

Each input file contains one test case. Each case occupies one line which contains an N (<= 10¹⁰⁰).

Output Specification:

For each test case, output in one line the digits of the sum in English words. There must be one space between two consecutive words, but no extra space at the end of a line.

Sample Input:

Sample Output:

one five

一开始我用的int来接受正整数，记得int的范围在32位机上是21亿，题目的正整数很明显超过这个范围，所以失败了好多次！！

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

void trans(int n)
{
    switch(n)
    {
        case 0: printf("zero");break;
        case 1: printf("one");break;
        case 2: printf("two");break;
        case 3: printf("three");break;
        case 4: printf("four");break;
        case 5: printf("five");break;
        case 6: printf("six");break;
        case 7: printf("seven");break;
        case 8: printf("eight");break;
        case 9: printf("nine");break;
    }
}
int main()
{

    int arr[112];
    char n[112];
    while(scanf("%s",n)!=EOF)
    {
        int i=0,sum=0;
        memset(arr,0,sizeof(arr));
        for(int k=0;k<strlen(n);k++)
        {
                sum+=n[k]-'0';
        }


        if(sum==0)
        {
            printf("zero");
        }
        else
        {
            while(sum)
            {
                arr[i] = sum%10;
                sum = sum/10;
                i++;
            }
            for(int j=i-1;j>=0;j--)
            {

                trans(arr[j]);
                if(j!=0)
                {
                    printf(" ");
                }


            }
        }

        printf("\n");
    }

    return 0;
}
