对于非负整数 X 而言,X 的数组形式是每位数字按从左到右的顺序形成的数组。例如,如果 X = 1231,那么其数组形式为 [1,2,3,1]。

给定非负整数 X 的数组形式 A,返回整数 X+K 的数组形式。

 

示例 1:

输入:A = [1,2,0,0], K = 34
输出:[1,2,3,4]
解释:1200 + 34 = 1234
示例 2:

输入:A = [2,7,4], K = 181
输出:[4,5,5]
解释:274 + 181 = 455
示例 3:

输入:A = [2,1,5], K = 806
输出:[1,0,2,1]
解释:215 + 806 = 1021
示例 4:

输入:A = [9,9,9,9,9,9,9,9,9,9], K = 1
输出:[1,0,0,0,0,0,0,0,0,0,0]
解释:9999999999 + 1 = 10000000000
 

提示:

1 <= A.length <= 10000
0 <= A[i] <= 9
0 <= K <= 10000
如果 A.length > 1,那么 A[0] != 0
