所以我知道我把它弄得乱七八糟，但它应该可以工作。我唯一的问题是我的 homeValue 输入没有得到返回值。因此，我的任何税款都不能适用。这是原始的问题陈述：

附言。很抱歉前几天直接问这个问题，我把我的闪存驱动器留在家里，这周晚些时候到期，所以我想今天把它贴出来。

你被要求为三县地区编写一个财产税程序。如果您住在查尔斯顿县，那么如果房屋价值低于或等于 50,000 美元，则您欠房屋价值的 1%。如果超过 50,000 美元但不超过 150,000 美元，您欠 1.50%，如果超过 150,000 美元，则欠 2%。如果您住在多切斯特县，那么如果低于或等于 50,000 美元，您就欠您房屋价值的 1.25%。如果超过 50,000 美元但不超过 150,000 美元，您欠 1.50%，如果超过 150,000 美元，则欠 1.75%。如果您住在伯克利县，那么如果房屋价值低于或等于 50,000 美元，则您欠 2%，如果大于 50,000 美元但不超过 150,000 美元，则为 2.25%，如果大于 150,000 美元，则为 2.75%。

在计划结束时，他们想查看房屋的价值、居住的县以及所欠的财产税。在代码中选择县时，必须使用 Switch 逻辑。
