Question

我有一个开始的Java程序，我一直致力于创建一个数字猜测程序，其中计算机猜测用户在一定范围内想到的数字。我到目前为止已经有了下面的程序，但需要帮助摆脱一些扭结/添加功能。 - 首先，我需要进行设置，以便提示用户并给出范围。它应该运行并产生这样的东西：欢迎来到这个有史以来第一个思维猜测计划！

请选择范围（大于1且不大于50）：32

您将选择1到32之间的数字......我会尝试猜测它。

根据我的每一个猜测，你会告诉我我是否太高（h或H），太低（l或L），匹配（m或M），或者你想退出（q或Q）。我的目标是尽可能少地猜测数字。

- 第二，游戏应该放弃并在失败之后重新启动，猜测，但由于某种原因，在第五次失败后，它再次提示第五次猜测，然后重新启动后 - 我需要防止这种情况，所以看起来应该是这样的：我的第四个猜测是17：h 我的猜测太高了？

我的第五个猜测是16：h ***这轮我很不走运。我放弃了。

让我们玩吧！

我的第一个猜测是10：等。

您尚未重置计数器guessNum

if (countdown == -1 && !input.equals("M") && !input.equals("m"))     {
                System.out.println("*** I am unlucky this round. I give     up.");
                losses++;
                guessNum = 0;
                break;

会做的伎俩。
