This is a basic guide to the course forum.
Posting here is similar to posting on Zhihu or Tieba, but please note:
- Make good use of the “Search” and “Advanced Search” functions; you can search by topic title or filter by tags. The search button is the magnifying‑glass icon in the upper‑right corner, and clicking the icon at the right end of the search bar opens advanced search.
- This semester’s teaching assistants are @storm314 @roland @evenwang @palpitate @wangying @greyishsong
@storm314 handles most submission‑related questions and various miscellaneous issues.
You can use Markdown syntax almost anywhere, for example:

When asking a question, please follow a few basic rules, otherwise the thread will be deleted:
- Do not post the complete answer to any lab problem, whether the answer is correct or not. If you want to ask a question related to specific code, paste only the part you are asking about; if you answer with code, do not post your entire code.
- Do not mention any fellow student’s personal information (student ID, name, class). For issues about submission errors or judge server failures, contact the TAs via QQ or private message on the site to avoid leaking personal data.
- Give your thread a clear, descriptive title. If your title is non‑indicative (e.g., “I have a question” or “Can’t finish the lab”), the TAs may not notice your problem for a long time.
- Adding tags helps the TA responsible for the corresponding lab quickly notice your question.
- Be friendly in replies; do not engage in personal attacks.
When an answer solves your problem, click the check mark at the lower right of that answer (shown in the orange box in the image below) to accept the answer and mark your question as “Resolved”:
