Solution

class Solution:
    def addToArrayForm(self, A: List[int], K: int) -> List[int]:
        carry = 0
        i = len(A) - 1

        while K or carry:
            if i < 0:
                A.insert(0, 0)
                i = 0

            val = K % 10

            carry, A[i] = divmod(A[i] + val + carry, 10)

            K //= 10
            i -= 1

        return A
