|
||
<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>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>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. 算法学习“三步走”<a class="headerlink" href="#024" title="Permanent link">¶</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>
