<p>本项目旨在创建一本开源、免费、对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,内容清晰易懂、学习曲线平滑,引导初学者探索数据结构与算法的知识地图。</li>
<li>源代码可一键运行,帮助读者在练习中提升编程技能,了解算法工作原理和数据结构底层实现。</li>
<li>提倡读者互助学习,欢迎大家在评论区提出问题与分享见解,在交流讨论中共同进步。</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的刷题量,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>
