【参考程序】

#include<iostream>

#include<algorithm>

#include<string>

#include<cstring>

using namespace std;

int main(){

int len=13;

int z,i,sum,now;

cin >>str1;

for (i=0;i<len;i++)

z++;

if (i!=len-1) sum=sum+z*now;

}

}

if (str1[len-1]=='X') now=10;

else now=str1[len-1]-'0';

if (sum%11==now)

cout <<"Right"<<endl;

else

for (i=0;i<len-1;i++)

if (sum!=10)

else cout <<"X"<<endl;

}

return 0;
