判断输进来的字符串是1 2 3的英文，当然会有一点错误产生。
只要判一下这三个单词的特点即可
#include<bits/stdc++.h>
using namespace std;
int main(){
int n;
double b;
int ans[33];
scanf("%d",&n);
while(n--)
{
memset(ans,0,sizeof(ans));
int res=0;
char s[11];
cin>>s;
if(strlen(s)==5)
{
cout<<"3"<<endl;
}
else{
if((s[0]=='o'&&s[1]=='n')||(s[0]=='o'&&s[2]=='e')||(s[1]=='n'&&s[2]=='e'))
cout<<"1"<<endl;
else cout<<"2"<<endl;
}
}
return 0;
}
