编译器用C++11，C++20有几个测试点过不了

#include<bits/stdc++.h>
using namespace std;
int main() {
    char a[13];
    unsigned int b;
    cin>>a;
    b=((a[0]-'0')+(a[2]-'0')*2+(a[3]-'0')*3+(a[4]-'0')*4+(a[6]-'0')*5+(a[7]-'0')*6+(a[8]-'0')*7+(a[9]-'0')*8+(a[10]-'0')*9)%11;
    if(b==a[12]-'0'||(a[12]=='X'&&b==10))
        cout<<"Right";
    else {
        cout<<a[0]<<a[1]<<a[2]<<a[3]<<a[4]<<a[5]<<a[6]<<a[7]<<a[8]<<a[9]<<a[10]<<a[11];
        if(b==10)
            cout<<'X';
        else
            cout<<b;
    }
    return 0;
}
