	/**
	* 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.
