989. Add to Array-Form of Integer

Description

For a non-negative integer X, the array-form of X is an array of its digits in left to right order.  For example, if X = 1231, then the array form is [1,2,3,1].

Given the array-form A of a non-negative integer X, return the array-form of the integer X+K.

 

Example 1:

Input: A = [1,2,0,0], K = 34

Output: [1,2,3,4]

Explanation: 1200 + 34 = 1234

Example 2:

Input: A = [2,7,4], K = 181

Output: [4,5,5]

Explanation: 274 + 181 = 455

Example 3:

Input: A = [2,1,5], K = 806

Output: [1,0,2,1]

Explanation: 215 + 806 = 1021

Example 4:

Input: A = [9,9,9,9,9,9,9,9,9,9], K = 1

Output: [1,0,0,0,0,0,0,0,0,0,0]

Explanation: 9999999999 + 1 = 10000000000

 

Note：

<li><code>1 &lt;= A.length &lt;= 10000</code></li>

<li><code>0 &lt;= A[i] &lt;= 9</code></li>

<li><code>0 &lt;= K &lt;= 10000</code></li>

<li>If <code>A.length &gt; 1</code>, then <code>A[0] != 0</code></li>
