Welcome to NJU SICP Wiki 2025

This wiki is an unofficial, student-built resource dedicated to Structure and Interpretation of Computer Programs (SICP). Our goal is to create a collaborative repository for valuable hints and solutions to the labs and homeworks.

💡 About This Project

This wiki is built and maintained by students, for students. We strictly adhere to academic integrity policies:

Before the due date (DDL): Only hints for the problems will be available.
After the due date (DDL): Full solutions will be released to aid in studying and understanding the material.

The wiki is powered by the following Python packages:

mkdocs
mkdocs-material
pymdown-extensions

🤝 How to Contribute

We welcome contributions from all students! If you have useful hints, clearer explanations, or solutions to share (post-DDL), please follow these guidelines:

Repository & File Edits

The source code for this wiki is hosted here:

Repository: https://git.nju.edu.cn/xmzheng/sicp-wiki-2025

You are only permitted to modify .md files located under the /docs directory.

Academic Integrity & Formatting

DDL Restriction: Before the DDL, you may only submit hints and conceptual explanations. Solutions are strictly forbidden.
Code Blocks: All code blocks must specify the language (e.g., python, scheme, sql) for proper syntax highlighting.
Local Test: Please test your changes locally (run mkdocs serve) before creating a Merge Request (MR). This ensures that complex \(\LaTeX\) formulas render correctly!
New Pages: When creating a new problem page, please start by copying the content from the provided template.md to ensure consistent formatting.

Merging Policy

We use a Merge Commit with Semi-Linear History to maintain a clean and traceable repository history:

A merge commit will be created for every merge.
A merge is only allowed if the source branch is up-to-date with its target.
If a semi-linear merge is not possible, users may be asked to rebase their branch.

We look forward to building this helpful resource together!
