这没毛病吧？？

#include<iostream>

using namespace std;
int main()
{
    string s,s1="";
    long long sum=0;
    cin>>s;
    int i=0,count=0;
    while(i<s.length())
    {
        if(s[i]>='0'&&s[i]<='9'&&count!=9)
        {
            count++;
            s1+=s[i];
        }
        i++;
    }
    for(int i=0;i<9;i++)
        sum+=(s[i]-'0')*(i+1);
    sum=sum%11;
    if((sum+'0')==s[s.length()-1])
        cout<<"Right";
    else
    {
        s[s.length()-1]=sum+'0';
        cout<<s;
    }
    return 0;
}
