Task 1 – Functor usage

Given a Result<List<Tower>, string> type that represents a list of towers, where Tower is a class containing properties such as Id, Name, and Damage, the task is to use the functor concept to apply a function to each tower that appends “(Upgraded)” to the end of its name to indicate that the tower has been upgraded:

public class Tower
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int Damage { get; set; }
}
public Result<List<Tower>, string> UpgradeTowers(List<Tower> towers)
{
