AC代码
```cpp
#include<bits/stdc++.h>
using namespace std;
int main()
{
int a,b,c,j2;
char j;
scanf("%d-%d-%d-%c",&a,&b,&c,&j);
if(j=='X') j2=10;
else{
j2=j-48;
}
//j是char类型的，需要转换成int
int b1=b/100,b2=b%100/10,b3=b%10;
int c1=c/10000,c2=c%10000/1000,c3=c%1000/100,c4=c%100/10,c5=c%10;
int x=a*1+b1*2+b2*3+b3*4+c1*5+c2*6+c3*7+c4*8+c5*9;
int e=x%11;
if(j2==e){
cout<<"Right";
}
else{
printf("%d-%d-%d-",a,b,c);
if(e==10) cout<<"X";
else cout<<e;
}
}
