I have seen that there is a question repository course in this website.
I want to ask if it is possible to access it (and it is possible to contribute).
What language(s) are you teaching? The only currently available question repository is for C questions, although a C++ repository with quite a few questions in German might be available if the question authors are happy to make it visible.
If you wish to have access to one of the repositories, please email email@example.com, including a brief explanation of why you require access, some evidence that you are a teacher and some form of email verification, such as a link to your home page on your institution's website.
I watched that there are repositories for C/C++ and Java and I want to obtain ideas (and testcases) in order to improve the number of exercises.
I will send and email to Richard asking if I can access to repositories :)
Thank you for everything :)
