我正在尝试比较两个树形图并比较关键字，然后对于两个地图的共同点，我想将这些值加在一起，然后将其输出到文本区域
到目前为止，我有两个可以成功工作的树图，但我不知道如何将它们与其他树进行比较。
到目前为止，这是我的代码：

这是我想出的一些伪代码，我不确定这是否可行或可行，但这是我想出的唯一方法
Get a word from mapOne
Check if word exists in mapTwo //This part is going to be the hardest I'm pretty sure
If word is found, get the key and set as freq2 then remove from mapTwo //Not sure if this is even needed
If word is not found in mapTwo, remove word from mapOne
Check mapOne.isEmpty if true, end loop
我的括号或其他东西似乎也有问题，我是编程新手，所以它可能是类似的东西，但是当我制作树形图时，我可以在同一个代码块中成功输出它们，但如果我去底部并尝试在其他地方输出它出现为空或未找到，就像地图只存在于该区域内，我知道我应该知道为什么会发生这种情况，但我不知道，我假设与公共或私人有关，或其他什么。
提前感谢您的帮助，抱歉，问题太大了，我很迷茫。
