I think it's supposed to merge two lists Not two integers So both left and right should be lists of... something

Couldn't you make it generic and contrain T to INumber<T> and make the two Lists be List<T>?

        static List<T> Merge<T>(List<T> left, List<T> right)
            where T : INumber<T>
        {
            List<T> result = new();

            while (left.Any() && right.Any())
            {
                if (left.First() <= right.First())
                {
                    result.Add(left.First());
                    left.Remove(left.First());
                }
                else
                {
                    result.Add(right.First());
                    right.Remove(right.First());
                }
            }

            return result;
        }

        static List<T> Merge<T>(List<T> left, List<T> right)
            where T : INumber<T>
        {
            List<T> result = new();

            while (left.Any() && right.Any())
            {
                if (left.First() <= right.First())
                {
                    result.Add(left.First());
                    left.Remove(left.First());
                }
                else
                {
                    result.Add(right.First());
                    right.Remove(right.First());
                }
            }

            return result;
        }

Perhaps something like this

Yes I agree. Then to check if a list is empty just do if(left.Count == 0) Though it is kinda strange they decided to name the two input lists “left” and “right” and not something more descriptive, like listA and listB, imo
