728. Self Dividing Numbers

 class Solution

 public:
     vector<int> selfDividingNumbers(int left, int right)
     {
         vector<int>res;
         for(int j=left;j<=right;j++)
         {
             if(judgesdnum(j))
                 res.push_back(j);
         }
         return res;
     }

     bool judgesdnum(int i)
     {
         int num=i;
         while(num>)
         {
             int cur=num%;
             if(cur==||i%cur!=)
                 return false;
             num/=;
         }
         return true;
     }
 };

写个判定函数，一个一个判定，问题不大
