'\b'这种偷鸡的写法是不行的
这样就行了
```cpp
#include <iostream>
#include <string>
using namespace std;
int main() {
string str;
int all = 0,j = 0;
cin >> str;
for (int i = 0; i <= 11; i++) {
if (str[i] != '-') {
j++;
all += int(str[i] - '0') * j;
}
}
all %= 11;
if (all == (str[12] - '0')||(all == 10 && str[12] == 'X'))
cout << "Right";
else if( all == 10)
{
for (int i = 0; i <= 11; i++)
cout << str[i];
cout << "X" << endl;
}
else
{
for (int i = 0; i <= 11; i++)
cout << str[i];
cout << all << endl;
}
return 0;
}
```

@[xuyao35](/user/1122193) 谢谢，解决了。看来对于洛谷的机制还是得好好研究一下。
