Statement
The array form of an integer is defined as an array of its digits ordered from left to right. For instance, the array form of [1, 3, 2, 1].
You are given num, which represents an integer in its array form, and an integer k. Compute the sum of the integer represented by num and k, then return the result as an array form representation.
Note:
numwill not contain leading zeros unless the number itself is zero.
