/**
 * You can brute force and increment/decrement the given number until you find a valid-all-even-digits
 * number, but the time complexity would be O(n) where n is value of the number.  Instead, you
 * can validate each digit starting with the highest power to come up with the nearest valid number.
 * Since you can make a number even by going up or down, both paths have to be considered.
 * 
 * For example, take 567;
 * 
 * It won't matter what you do with '67' because '5' will always be invalid.  So you have to make it even.
