string convertToBase7(int num)

     {

         if (num == ) return "";

         string ret = "";

         int temp = num;

         if (num < ) num = -num;

         while (num)

         {

             ret.insert(ret.begin(), num %  + '');
            //ret = to_string(num % 7) + ret;//to_string用法

             num /= ;

         }

         if (temp < )ret.insert(ret.begin(), '-');
