如何限制用户在每个inputFirstTag，inputSecondTag，inputThirdTag上的不同“技能”上花费“标记”
一切正常，直到第二轮才会出现丑陋的头脑。 inputSecondTag可以成为inputFirstTag的副本，inputThirdTag可以成为inputSecondTag的副本。

答案 0 :(得分：2)
没有用一长串代码压倒你：
您可以创建“taggedSkills”的Set数据结构。最初，此Set为空。如果用户标记了技能，则该技能会添加到该组中。
然后，如果用户的第二个标记与第一个标记的技能相同，则程序可以检查“设置”并要求用户使用新技能再次尝试，而不是添加重复标记。与第三项技能相同。
