@ZZYjinitaimei 仅供参考

#include<iostream>
#include<cstring>
using namespace std;
int main(){
    char s[20];
    cin>>s;
    int len=strlen(s);
    int k=1,y=0;
    for(int i=0;i<=len-2;i++){
        if(s[i]=='-'){
            continue;
        }else{
            y=y+k*(s[i]-'0');
            k++;
        }
    }
    y=y%11;
    char c=y+'0';
    if(y==10){
        c='X';
    }
    if(c==s[len-1]){
        cout<<"Right";
    }else{
        for(int i=0;i<=len-2;i++){
            cout<<s[i];
        }
        cout<<c;
    }
    return 0;
