<p>视频和图片相比于文字的信息密度和结构化程度更高,更容易让人理解。在本书中,重点和难点知识会主要以动画、图解的形式呈现,而文字的作用则是作为动画和图的解释与补充。</p>
<p>在阅读本书的过程中,若发现某段内容提供了动画或图解,<strong>建议你以图为主线</strong>,将文字内容(一般在图的上方)对齐到图中内容,综合来理解。</p>

<p class="admonition-title">前置工作</p>
<p>如果没有本地编程环境,可以参照下节 <a href="https://www.hello-algo.com/chapter_preface/installation/">编程环境安装</a></p>
</div>
<h3 id="_1">下载代码仓<a class="headerlink" href="#_1" title="Permanent link">&para;</a></h3>
<p>如果已经安装 <a href="https://git-scm.com/downloads">Git</a> ,可以通过命令行来克隆代码仓。</p>

</code></pre></div>
<p>当然你也可以点击“Download ZIP”直接下载代码压缩包解压即可。</p>
<p><img alt="download_code" src="../suggestions.assets/download_code.png" /></p>
<h3 id="_2">运行源代码<a class="headerlink" href="#_2" title="Permanent link">&para;</a></h3>
<p>本书提供配套 Java, C++, Python 代码仓(后续可能拓展支持语言)。书中的代码栏上若标有 <code>*.java</code> , <code>*.cpp</code> , <code>*.py</code> ,则可在仓库 codes 文件夹中找到对应的 <strong>代码源文件</strong></p>
<p><img alt="code_md_to_repo" src="../suggestions.assets/code_md_to_repo.png" /></p>
<p>这些源文件中包含详细注释,配有测试样例,可以直接运行,帮助你省去不必要的调试时间,可以将精力集中在学习内容上。</p>
<p><img alt="running_code" src="../suggestions.assets/running_code.gif" /></p>
<div class="admonition tip">
<p class="admonition-title">代码学习建议</p>
<p>若学习时间紧张,<strong>请至少将所有代码通读并运行一遍</strong>。若时间允许,<strong>强烈建议对照着代码自己敲一遍</strong>,逐渐锻炼肌肉记忆。相比于读代码,写代码的过程往往能带来新的收获。</p>

<p>阅读本书时,请不要“惯着”那些弄不明白的知识点。如果有任何疑惑,<strong>可以在评论区留下你的问题</strong>,小伙伴们和我都会给予解答(您一般 3 天内会得到回复)。</p>
<p>同时,也希望你可以多花时间逛逛评论区。一方面,可以看看大家遇到了什么问题,反过来查漏补缺,这往往可以引起更加深度的思考。另一方面,也希望你可以慷慨地解答小伙伴们的问题、分享自己的见解,大家一起加油与进步!</p>

<h2 id="024">0.2.4. &nbsp; 算法学习“三步走”<a class="headerlink" href="#024" title="Permanent link">&para;</a></h2>
<p><strong>第一阶段,算法入门,也正是本书的定位</strong>。熟悉各种数据结构的特点、用法,学习各种算法的工作原理、用途、效率等。</p>
<p><strong>第二阶段,刷算法题</strong>。可以先从热门题单开刷,推荐 <a href="https://leetcode.cn/problem-list/xb9nqhhg/">剑指 Offer</a><a href="https://leetcode.cn/problem-list/2cktkvj/">LeetCode 热题 HOT 100</a> ,先积累至少 100 道题量,熟悉大多数的算法问题。刚开始刷题时,“遗忘”是最大的困扰点,但这是很正常的,请不要担心。学习中有一种概念叫“周期性回顾”,同一道题隔段时间做一次,当做了三遍以上,往往就能牢记于心了。</p>
<p><strong>第三阶段,搭建知识体系</strong>。在学习方面,可以阅读算法专栏文章、解题框架、算法教材,不断地丰富知识体系。在刷题方面,可以开始采用进阶刷题方案,例如按专题分类、一题多解、一解多题等,刷题方案在社区中可以找到一些讲解,在此不做赘述。</p>
