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