A 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 == 0,
128 % 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.
Input: left = 1, right = 22 Output: [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.
