CodingBat: DividesSelf
We'll say that a positive int divides itself if every digit in the number divides into the number evenly. So for example 128 divides itself since 1, 2, and 8 all divide into 128 evenly. We'll say that 0 does not divide into anything evenly, so no number with a 0 digit divides itself. Note: use % to get the rightmost digit, and / to discard the rightmost digit.
Example:
dividesSelf(128) → true
dividesSelf(12) → true
dividesSelf(120) → false
