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 = 34Output:[1,2,3,4]Explanation:1200 + 34 = 1234

**Example 2:**

Input:num = [2,7,4], k = 181Output:[4,5,5]Explanation:274 + 181 = 455

**Example 3:**

Input:num = [2,1,5], k = 806Output:[1,0,2,1]Explanation:215 + 806 = 1021

**Example 4:**

Input:num = [9,9,9,9,9,9,9,9,9,9], k = 1Output:[1,0,0,0,0,0,0,0,0,0,0]Explanation:9999999999 + 1 = 10000000000

**Constraints:**

`1 <= num.length <= 10`

^{4}`0 <= num[i] <= 9`

`num`

does not contain any leading zeros except for the zero itself.`1 <= k <= 10`
