如此即可
#include<bits/stdc++.h>
using namespace std;
char a[14];
long long ans;
int b,len,temp,t=1;
int main()
{
    cin.getline(a,14);
    len=strlen(a);
    for(int i=0;i<len-2;i++){
        if(a[i]!='-'){
            temp=a[i]-'0';
            b+=temp*t;
            t++;
        }
    }
    b%=11;
    if(b!=10){
        if(a[len-1]-'0'==b) cout<<"Right";
        else{
            for(int i=0;i<len-1;i++) cout<<a[i];
            cout<<b;
        }
    }
    else{
        if(a[len-1]=='X') cout<<"Right";
        else{
            for(int i=0;i<len-1;i++) cout<<a[i];
            cout<<'X';
        }
    }
    return 0;
}
