<p class="admonition-title">Tip</p>
<p>为了获得最佳的阅读体验，建议你通读本节内容。</p>
</div>
<h2 id="021">0.2.1 &nbsp; 行文风格约定<a class="headerlink" href="#021" title="Permanent link">&para;</a></h2>
<ul>
<li>标题后标注 <code>*</code> 的是选读章节，内容相对困难。如果你的时间有限，可以先跳过。</li>
<li>专业术语会使用黑体（纸质版和 PDF 版）或添加下划线（网页版），例如<u>数组（array）</u>。建议记住它们，以便阅读文献。</li>
<li>重点内容和总结性语句会 <strong>加粗</strong>，这类文字值得特别关注。</li>
<li>有特指含义的词句会使用“引号”标注，以避免歧义。</li>
<li>当涉及编程语言之间不一致的名词时，本书均以 Python 为准，例如使用 <code>None</code> 来表示“空”。</li>
<li>本书部分放弃了编程语言的注释规范，以换取更加紧凑的内容排版。注释主要分为三种类型：标题注释、内容注释、多行注释。</li>
</ul>

<p>相较于文字，视频和图片具有更高的信息密度和结构化程度，更易于理解。在本书中，<strong>重点和难点知识将主要通过动画以图解形式展示</strong>，而文字则作为解释与补充。</p>
<p>如果你在阅读本书时，发现某段内容提供了如图 0-2 所示的动画图解，<strong>请以图为主、以文字为辅</strong>，综合两者来理解内容。</p>

<p>本书的配套代码托管在 <a href="https://github.com/krahets/hello-algo">GitHub 仓库</a>。如图 0-3 所示，<strong>源代码附有测试样例，可一键运行</strong>。</p>
<p>如果时间允许，<strong>建议你参照代码自行敲一遍</strong>。如果学习时间有限，请至少通读并运行所有代码。</p>
<p>与阅读代码相比，编写代码的过程往往能带来更多收获。<strong>动手学，才是真的学</strong>。</p>

<p align="center"> 图 0-3 &nbsp; 运行代码示例 </p>
<p>运行代码的前置工作主要分为三步。</p>
<p><strong>第一步：安装本地编程环境</strong>。请参照附录所示的<a href="https://www.hello-algo.com/chapter_appendix/installation/">教程</a>进行安装，如果已安装，则可跳过此步骤。</p>
<p><strong>第二步：克隆或下载代码仓库</strong>。前往 <a href="https://github.com/krahets/hello-algo">GitHub 仓库</a>。如果已经安装 <a href="https://git-scm.com/downloads">Git</a> ，可以通过以下命令克隆本仓库：</p>
<div class="highlight"><pre><span></span><code><a id="__codelineno-14-1" name="__codelineno-14-1" href="#__codelineno-14-1"></a>git<span class="w"> </span>clone<span class="w"> </span>https://github.com/krahets/hello-algo.git
</code></pre></div>
<p>当然，你也可以在图 0-4 所示的位置，点击“Download ZIP”按钮直接下载代码压缩包，然后在本地解压即可。</p>
<p><a class="glightbox" href="../suggestions.assets/download_code.png" data-type="image" data-width="100%" data-height="auto" data-desc-position="bottom"><img alt="克隆仓库与下载代码" class="animation-figure" src="../suggestions.assets/download_code.png" /></a></p>
<p align="center"> 图 0-4 &nbsp; 克隆仓库与下载代码 </p>
<p><strong>第三步：运行源代码</strong>。如图 0-5 所示，对于顶部标有文件名称的代码块，我们可以在仓库的 <code>codes</code> 文件夹内找到对应的源代码文件。源代码文件可一键运行，将帮助你节省不必要的调试时间，让你能够专注于学习内容。</p>

<p>除了本地运行代码，<strong>网页版还支持 Python 代码的可视化运行</strong>（基于 <a href="https://pythontutor.com/">pythontutor</a> 实现）。如图 0-6 所示，你可以点击代码块下方的“可视化运行”来展开视图，观察算法代码的执行过程；也可以点击“全屏观看”，以获得更好的阅览体验。</p>

<h2 id="025">0.2.5 &nbsp; 算法学习路线<a class="headerlink" href="#025" title="Permanent link">&para;</a></h2>
<p>从总体上看，我们可以将学习数据结构与算法的过程划分为三个阶段。</p>
<ol>
<li><strong>阶段一：算法入门</strong>。我们需要熟悉各种数据结构的特点和用法，学习不同算法的原理、流程、用途和效率等方面的内容。</li>
<li><strong>阶段二：刷算法题</strong>。建议从热门题目开刷，先积累至少 100 道题目，熟悉主流的算法问题。初次刷题时，“知识遗忘”可能是一个挑战，但请放心，这是很正常的。我们可以按照“艾宾浩斯遗忘曲线”来复习题目，通常在进行 3～5 轮的重复后，就能将其牢记在心。推荐的题单和刷题计划请见此 <a href="https://github.com/krahets/LeetCode-Book">GitHub 仓库</a>。</li>
<li><strong>阶段三：搭建知识体系</strong>。在学习方面，我们可以阅读算法专栏文章、解题框架和算法教材，以不断丰富知识体系。在刷题方面，可以尝试采用进阶刷题策略，如按专题分类、一题多解、一解多题等，相关的刷题心得可以在各个社区找到。</li>
</ol>
<p>如图 0-8 所示，本书内容主要涵盖“阶段一”，旨在帮助你更高效地展开阶段二和阶段三的学习。</p>
