self-dividing number is a number that is divisible by every digit it contains.

For example, 128 is a self-dividing number because 128 % 1 == 0128 % 2 == 0, and 128 % 8 == 0.

Also, a self-dividing number is not allowed to contain the digit zero.

Given a lower and upper number bound, output a list of every possible self dividing number, including the bounds if possible.

Example 1:

Input: left = 1, right = 22Output: [1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 15, 22]

Note:

  • The

  •  boundaries of each input argument are 1 <= left <= right <= 10000.



    即遍历数组,对每个数字进行判断,符合要求的推进要返回的数组。

    判断条件的设置使用循环的方式,循环终止的条件应当是每次取余得一位数,那一位数为零则判断停止,循环内部拿到那一位数后对整体数字进行取余,若不为零同样跳出循环。

    出循环后通过判断剩下的位数的数字是否空了,若空了则说明符合条件,推入返回数字,否则不满足。

    class Solution {public:    vector<int> selfDividingNumbers(int left, int right) {        vector<int> re;        for(int i=left; i<=right;i++){            int temp=i;            while(temp !=0 && temp %10 != 0){                if(i % (temp % 10) != 0) break;                temp = temp / 10;            }            if(temp == 0) re.push_back(i);        }        return re;    }};
