```c
#include<bits/stdc++.h>
using namespace std;
char dic[30][20]={"zero","one","two","three","four","five","six","seven","eight","nine","ten","eleven","twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen", "twenty","a","both","another","first","second","third"};//对应
int di[30]={0,1,4,9,16,25,36,49,64,81,00,21,44,69,96,25,56,89,24,61,0,1,4,1,1,4,9};
unsigned long long int a[10],top,flag;
int i,j;
char s[100];
int main()
{
for(i=1;i<=6;i++)
{
scanf("%s",&s);//%s读入遇到空格就停止
for(j=1;j<=26;j++)
{
if(!strcmp(s,dic[j]))//strcmp(s1,s2);如果他们相同，返回0
{
a[++top]=di[j];//用数组存储
break;//立即停止寻找
}
}
}
sort(a+1,a+top+1);//贪心，使越小的数越靠前输出
for(i=1;i<=top;i++)
{
if(flag)//如果不是第一位
{
printf("%.2d",a[i]);//限制格式输出
}
else
{
if(a[i])
{
printf("%d",a[i]);
flag=1;
}
}
}
if(!flag)printf("0");//特判
return 0;
}

感谢回复！
我有一个问题：zero需要处理吗?

需要的
```c
if(!flag)printf("0");//特判
```
