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
Input: num = [1,2,0,0], k = 34
Output: [1,2,3,4]
Explanation: 1200 + 34 = 1234
Solution
/**
* @param {number[]} num
* @param {number} k
* @return {number[]}
*/
var addToArrayForm = function(num, k) {
let result = []
for(let i = num.length - 1; i >= 0; i--) {
result.push((num[i] + k) % 10);
k = parseInt((num[i] + k) / 10);
}
while(k) {
result.push(k % 10);
k = parseInt(k / 10);
}
return result.reverse()
};
