<h1 id="01">0.1 &nbsp; 关于本书<a class="headerlink" href="#01" title="Permanent link">&para;</a></h1>
<p>本项目旨在创建一本开源、免费、新手友好的数据结构与算法入门教程。</p>
<ul>
<li>全书采用动画图解，结构化地讲解数据结构与算法知识，内容清晰易懂、学习曲线平滑。</li>
<li>算法源代码皆可一键运行，支持 Python、C++、Java、C#、Go、Swift、JavaScript、TypeScript、Dart、Rust、C、Zig 等语言。</li>
<li>鼓励读者在章节讨论区互帮互助、共同进步，提问与评论通常可在两日内得到回复。</li>
</ul>
<h2 id="011">0.1.1 &nbsp; 读者对象<a class="headerlink" href="#011" title="Permanent link">&para;</a></h2>
<p>若你是算法初学者，从未接触过算法，或者已经有一些刷题经验，对数据结构与算法有模糊的认识，在会与不会之间反复横跳，那么本书正是为你量身定制的！</p>
<p>如果你已经积累一定刷题量，熟悉大部分题型，那么本书可助你回顾与梳理算法知识体系，仓库源代码可以当作“刷题工具库”或“算法字典”来使用。</p>
<p>若你是算法大神，我们期待收到你的宝贵建议，或者<a href="https://www.hello-algo.com/chapter_appendix/contribution/">一起参与创作</a>。</p>

<p>在本书的创作过程中，我得到了许多人的帮助，包括但不限于：</p>
<ul>
<li>感谢我在公司的导师李汐博士，在一次畅谈中你鼓励我“快行动起来”，坚定了我写这本书的决心；</li>
<li>感谢我的女朋友泡泡作为本书的首位读者，从算法小白的角度提出许多宝贵建议，使得本书更适合新手阅读；</li>
<li>感谢腾宝、琦宝、飞宝为本书起了一个富有创意的名字，唤起大家写下第一行代码 "Hello World!" 的美好回忆；</li>
<li>感谢校铨在知识产权方面提供的专业帮助，这对本开源书的发展起到了重要的作用；</li>
<li>感谢苏潼为本书设计了精美的封面和 logo ，并在我的强迫症下多次耐心修改；</li>
<li>感谢 @squidfunk 提供的写作排版建议，以及他开发的开源文档主题 <a href="https://github.com/squidfunk/mkdocs-material/tree/master">Material-for-MkDocs</a> 。</li>
</ul>
<p>在写作过程中，我阅读了许多关于数据结构与算法的教材和文章。这些作品为本书提供了优秀的范本，确保了本书内容的准确性与品质。在此感谢所有老师和前辈们的杰出贡献！</p>
<p>本书倡导手脑并用的学习方式，在这一点上深受<a href="https://github.com/d2l-ai/d2l-zh">《动手学深度学习》</a>的启发。在此向各位读者强烈推荐这本优秀的著作。</p>
<p><strong>衷心感谢我的父母，正是你们一直以来的支持与鼓励，让我有机会做这件富有趣味的事</strong>。</p>
