Add to Array-Form of Integer
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]1200 + 34 = 1234.
Example 2
Input
num = [2,7,4], k = 181Output
[4,5,5]274 + 181 = 455.
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
