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.

Examples

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
