Addition With Arrays

Given two integers represented in arrays, A and B. Where each digit of the integer occupies an index in the array. Write an NPM module that allows a developer to produce the summation of integers A + B as array C.

The resulting array C should be formatted in the same way as A and B, each digit should occupy an index.

Examples

   123 [1, 2, 3]
 + 456 [4,5,6]
 -------
   579 [5,7,9]

Another example:

    11
 +  15
 -------
    26

A final example:

    111
 +   15
 -------
    126

Double Digit number

  123
+ 398
------
  521

It is important that you return an array as the final result.

You can make the assumption that the two method arguments will always be arrays of integers. Don't worry about validating input..
