Description
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 <= 10^4
0 <= num[i] <= 9
num
does not contain any leading zeros except for the zero itself.
1 <= k <= 10^4
