The array-form of an integer num is an array representing its digits in left to right order.
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
- 1 <= num.length <= 10^4
- 0 <= num[i] <= 9
- num does not contain any leading zeros except for the zero itself.
- 1 <= k <= 10^4
