数据范围是18位，把每一位加起来的和最多9*18 = 162

所以只需考虑n-162 ～ n的数即可，暴力解决

 #include <iostream>
 using namespace std;
 typedef long long ll;

 ll Div(ll n)
 {
     ll num = ;
     while (n) {
         num += n % ;
         n /= ;
     }
     return num;
 }

 int main()
 {
     ios::sync_with_stdio(false);
     cin.tie();
     int t;
     cin >> t;
     while (t--) {
         ll n;
         cin >> n;
         bool flag = false;
         for (ll i = max(0ll, n - ); i <= n; i++) {
             if (Div(i) + i == n) {
                 cout << i << endl;
                 flag = true;
                 break;
             }
         }
         if (!flag)
             cout << "Stupid SiriusRen" << endl;
     }
     return ;
 }
