好，这是一个基本的作业问题，您可以在网络上找到很多有关如何执行此操作的示例.在我看来，最合乎逻辑的方法是将数字转换成字符串然后一次解析一次.

OK, this is a basic homework question, and you can find plenty of examples on the web for how to do it. The most logical way, in my mind, is to turn the number into a string then parse it one bit at a time.

逻辑与您在大脑隐式应用的逻辑相同.''重新读取这些数字.因此，将其明确并告知计算机，即编写自己的应用程序以执行任务.
:)

The logic is the same your brain implicitely apply while you''re reading such numbers. So make it explicit and tell to your computer, i.e. code your own application to perform the task.
