❔ Circle

                        // In Main (here), add code to case 5 of the switch.
                        //      •    Clear the screen.
                        //      •    Generate a random Point2D point with an x, y anywhere in the console. This point will be the center position of the circle.
                        //      •    Calculate a random radius – ensure that it will NOT extend the circle beyond the bounds of the console.
                        //      •    Use the point and radius to create a Circle instance with any color you want.
                        //      •    Call Draw on the Circle instance.

                        Console.Clear();
                        rnd = new Random();
                        int x = rnd.Next(0, Console.WindowWidth-1);
                        int y = rnd.Next(0, Console.WindowHeight-1);
                        Point2D point = new Point2D(x, y);
                        int radius = rnd.Next();
                        while(x + radius > Console.WindowWidth || y + radius > Console.WindowHeight || x - radius < 0 || y - radius < 0)
                        {
                            radius = rnd.Next(1, Console.WindowWidth - x);
                        }
                        Circle circle = new Circle(radius, point, ConsoleColor.Magenta);
                        circle.Draw();
                        break;

                        Console.Clear();
                        rnd = new Random();
                        int x = rnd.Next(0, Console.WindowWidth-1);
                        int y = rnd.Next(0, Console.WindowHeight-1);
                        Point2D point = new Point2D(x, y);
                        int radius = rnd.Next();
                        while(x + radius > Console.WindowWidth || y + radius > Console.WindowHeight || x - radius < 0 || y - radius < 0)
                        {
                            radius = rnd.Next(1, Console.WindowWidth - x);
                        }
                        Circle circle = new Circle(radius, point, ConsoleColor.Magenta);
                        circle.Draw();
                        break;

its an assignment I already turned in but would like some feedback as to why my check for radius boundary has been very wonky, i still had exceptions being thrown for it being out of bounds on my screen.

❔ Learning binary searching

i linked the txt file for my entire page the part im stuck on is

        //
        // Part B-2: FindHero
        //      The method should have a string parameter for the name of the hero to find.
        //      Call the BinarySearch method from part A-3.
        //      Print the result.
        //      If the found index is -1,
        //          print "<insert heroName> is not found"
        //      otherwise
        //          print "<insert heroName> was found at index <insert found index>"
        //

        public void FindHero(String hero)
        {
            BinarySearch(_heroes);
        }

for (int i = 0; i < _heroes.Count; i++) { if (_heroes[i].Name.StartsWith(name, StringComparison.OrdinalIgnoreCase)) { _heroRem.Add(_heroes[i]); _heroes.RemoveAt(i); } } }
