❔ How to return a generic interface whose only parameter is determined on runtime?

    private static IProblem<T>? GetProblem<T>(int day, T type)
    {
        try
        {
            var instance = Activator.CreateInstance(Problems[day]);
            return (IProblem<T>?)instance;
        }
        catch (Exception e)
        {
            Console.Error.WriteLine(e);
            return null;
        }
    }

    private static IProblem<T>? GetProblem<T>(int day, T type)
    {
        try
        {
            var instance = Activator.CreateInstance(Problems[day]);
            return (IProblem<T>?)instance;
        }
        catch (Exception e)
        {
            Console.Error.WriteLine(e);
            return null;
        }
    }
