    989 - Add to Array-Form of Integer.

    Easy

    The array-form of an integer num is an array representing its digits in left to right order.

    • For example, for num = 1321, the array form is [1,3,2,1].

    Given num, the array-form of an integer, and an integer k, return the array-form of the integer num + k.

    Example 1:

    Input: num = 1,2,0,0, k = 34

    Output: 1,2,3,4

    Explanation: 1200 + 34 = 1234

    Example 2:

    Input: num = 2,7,4, k = 181

    Output: 4,5,5

    Explanation: 274 + 181 = 455

    Example 3:

    Input: num = 2,1,5, k = 806

    Output: 1,0,2,1

    Explanation: 215 + 806 = 1021

    Constraints:

    • <code>1 <= num.length <= 10<sup>4</sup></code>

    • 0 &lt;= num[i] &lt;= 9

    • num does not contain any leading zeros except for the zero itself.

    • <code>1 <= k <= 10<sup>4</sup></code>
