# Approach\n<!-- Describe your approach to solving the problem. -->\n- First I converted list into string format in order to make it as number.\n- Then I added the num and K and then converted the result into string again to convert from string format to list and assigned to str_list.\n- Later converted the str_list into int by using map function and assigned it to final_str_list and returned it.\n\n# Code\n```\nclass Solution:\n    def addToArrayForm(self, num: List[int], k: int) -> List[int]:\n        s = ""\n        for i in num:\n            s+=str(i)\n        str_list = " ".join(str(int(s)+k)).split()\n        final_list = list(map(int,str_list))\n        return final_list\n```\n# Please upvote if you find the solution helpful.
