-1

这将是我著名的 8x8 甲板骑士之旅的代码。所以，我的代码的主要思想是：我们将从 Turns 中选择我们的目的地，用 isPossible 检查它，然后递归到它，将此单元格标记为“1”。所以，检查每个单元格，如果我们将在 64 的单元格中 - 返回 true。但是我的代码会无限递归，我无法调试它，任何建议都将不胜感激。

    static void Main(string[] args)

        int x = 0;
        int y = 0;
        Console.WriteLine("Enter X and press enter");
        x = Int32.Parse(Console.ReadLine());
        Console.WriteLine("Enter Y and press enter");
        y = Int32.Parse(Console.ReadLine());
        TurnVariation Turns = new TurnVariation(); 
        EmptyBoard Board = new EmptyBoard();
        if (TryPut.Put(Board, x, y, Turns, 1, false))
        {
            Console.WriteLine("МОЖНА!!!!");
        }
        else

            Console.WriteLine("NET!!");

我认为您的问题是您对 count<64 的测试，但您从未分配给 count。您只需将（按值！）'Count + 1' 传递给 put 方法。您可能认为这将被写回 count 变量。但事实并非如此...

请注意，调试是您需要学习的第一项技能！
