commonDigit

Define a function that when passed two integers (say a, b), returns true if they have any digit in common, false otherwise. Note: you should return false if either number is 0, because 0 by itself, contains no digit.

commonDigit(1729, 861350) → true
commonDigit(17, 29) → false
commonDigit(172, 91) → true
