Given an array of integers of any length, return an array that has 1 added to the value represented by the array.
- the array can't be empty
- only non-negative, single digit integers are allowed
- Return nil for invalid inputs.
For example the array [2, 3, 9] equals 239, adding one would return the array [2, 4, 0].
[4, 3, 2, 5] would return [4, 3, 2, 6]
