A self-dividing number is a number that is divisible by every digit it contains.
- For example,
128is a self-dividing number because128 % 1 == 0,128 % 2 == 0, and128 % 8 == 0.
A self-dividing number is not allowed to contain the digit zero.
Given two integers left and right, return a list of all the self-dividing numbers in the range [left, right] (both inclusive).
Example 1:
Input: left = 1, right = 22 Output: [1,2,3,4,5,6,7,8,9,11,12,15,22]
Example 2:
Input: left = 47, right = 85 Output: [48,55,66,77]
Constraints:
1 <= left <= right <= 104
Hints
Hint 1
For each number in the range, check whether it is self dividing by converting that number to a character array (or string in Python), then checking that each digit is nonzero and divides the original number.
