Hello and welcome to discussion board of Software Foundations! Writing Coq code is enjoyable, but some of the exercises are really hard. Here, we can discuss these problems. Attention: You shouldn't copy these solutions directly! Use them as a hint in case you get stuck. If you have questions about these solutions, or if you have a better one, feel free to leave a comment.
您好,欢迎来到《软件基础》的讨论板!书写 Coq 的代码给了我们极致丝滑的体验,但是有的题想了一天也毫无头绪。这里将是一个讨论这些问题的平台! 注意:您不能直接抄写这些答案! 在你遇到困难的时候,可以把他们作为一个提示。如果你对解法有任何的问题,或是你有更好的解法,欢迎在评论区留言。
If you are the teacher of a relevant course and would like me to close this discussion board, please contact me (vbcpascal@outlook.com). I will privatize it unconditionally.
