Here is an easy to understand 1 liner\n\n# Approach\n1. Convert the num array to a string\n2. Parse as a number\n3. Add k\n4. Convert value to string\n5. Convert each element to an int\n6. Build list to return\n\n# Code\n```\nusing System.Numerics;\npublic class Solution {\n    public IList<int> AddToArrayForm(int[] num, int k) {\n        return (BigInteger.Parse(string.Join("", num.Select(x => x))) + k).ToString().Select(x => int.Parse(x.ToString())).ToList();\n    }\n}\n```
