@nahida_badminton

int a = sum % 11;
    if (ma == 'X' && a == 10){
        cout << "Right";
    } else if (ma - '0' == a){
        cout << "Right";
    } else {

    }

你的判断错了

@lvzekai 大佬，是第几个判断啊

@nahida_badminton 你可以看看我的代码

#include<bits/stdc++.h>
using namespace std;
typedef long long ll;
ll n,s,ans=1;
string a;
int main()
{
    ios::sync_with_stdio(false);
    cin.tie(0);
    cout.tie(0);
    cin>>a;
    n=a.size()-1;
    for(int i=0;i<n;i++)
    {
        if(a[i]>='0'&&a[i]<='9')
        {
            s=s+(a[i]-'0')*ans;
            ans++;
            s%=11;
        }
    }
    if((a[n]-'0'==s)||(a[a.size()-1]=='X'&&s==10))
    {
        cout<<"Right"<<"\n";
    }
    else
    {
        for(int i=0;i<n;i++)
        {
            cout<<a[i];
        }
        if(s==10)
        {
            cout<<"X"<<"\n";
        }
        else
        {
            cout<<s<<"\n";
        }
    }
    return 0;
}

谢谢大佬，我发现问题了，是在输入的时候忘记声明域宽了
