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:

  • 1 <= num.length <= 104
  • 0 <= num[i] <= 9
  • num does not contain any leading zeros except for the zero itself.
  • 1 <= k <= 104
