直接拿万能头，string 类型就好了，没必要那么麻烦。
# AC 代码
```cpp
#include<bits/stdc++.h>
using namespace std;
int main(){
string str,truely;
int flag=0,num=1;
cin>>str;
truely=str;
for (int i=0;i<12;++i){
if(str[i]=='-')continue;
flag=flag+(str[i]-'0')*num;
num++;
}
if(flag%11==10)
truely[12]='X';
else
truely[12]=flag%11+'0';
if(str!=truely){
cout<<truely<<endl;
}else printf("Right");
return 0;
}
```
