# labuladong 的算法笔记
本仓库总共 60 多篇原创文章，都是基于 LeetCode 的题目，涵盖了所有题型和技巧，而且一定要做到**举一反三，通俗易懂**，绝不是简单的代码堆砌，后面有目录。
我先吐槽几句。**刷题刷题，刷的是题，培养的是思维，本仓库的目的就是传递这种算法思维**。我要是只写一个包含 LeetCode 题目代码的仓库，有个锤子用？没有思路解释，没有思维框架，顶多写个时间复杂度，那玩意一眼就能看出来。
只想要答案的话很容易，题目评论区五花八门的答案，动不动就秀 python 一行代码解决，有那么多人点赞。问题是，你去做算法题，是去学习编程语言的奇技淫巧的，还是学习算法思维的呢？你的快乐，到底源自复制别人的一行代码通过测试，已完成题目 +1，还是源自自己通过逻辑推理和算法框架不看答案写出解法？
网上总有大佬喷我，说我写的东西太基础，要么说不能借助框架思维来学习算法。我只能说大家刷算法就是找工作吃饭的，不是打竞赛的，我也是一路摸爬滚打过来的，我们要的是清楚明白有所得，不是故弄玄虚无所指。
不想办法做到通俗易懂，难道要上来先把《算法导论》吹上天，然后把人家都心怀敬仰地劝退？
**做啥事情做多了，都能发现套路的，我把各种算法套路框架总结出来，相信可以帮助其他人少走弯路**。我这个纯靠自学的小童鞋，花了一年时间刷题和总结，自己写了一份算法小抄，后面有目录，这里就不废话了。
## 在开始学习之前
**1、先给本仓库点个 star，满足一下我的虚荣心**，文章质量绝对值你一个 star。我还在继续创作，给我一点继续写文的动力，感谢。
**2、建议收藏我的在线网站，每篇文章开头都有对应的力扣题目链接，可以边看文章边刷题，一共可以手把手带你刷 500 道题目**：

## labuladong 刷题全家桶简介
### 一、算法可视化面板
我的算法网站、所有配套插件都集成了一个算法可视化工具，可以对数据结构和递归过程进行可视化，大幅降低理解算法的难度。几乎每道题目的解法代码都有对应的可视化面板，具体参见下方介绍。
### 二、学习网站
内容当然是我的系列算法教程中最核心的部分，我的算法教程都发布在网站 [labuladong.online](https://labuladong.online/algo/) 上，相信你会未来会在这里花费大量的学习时间，而不是仅仅加入收藏夹~
![](https://labuladong.github.io/pictures/简介/web_intro1.jpg)
### 三、Chrome 插件
**主要功能**：Chrome 插件可以在中文版力扣或英文版 LeetCode 上快捷查看我的「题解」或「思路」，并添加了题目和算法技巧之间的引用关系，可以和我的网站/公众号/课程联动，给我的读者提供最丝滑的刷题体验。安装使用手册见下方目录。
![](https://labuladong.github.io/pictures/简介/chrome_intro.jpg)
### 四、vscode 插件
**主要功能**：和 Chrome 插件功能基本相同，习惯在 vscode 上刷题的读者可以使用该插件。安装使用手册见下方目录。
![](https://labuladong.github.io/pictures/简介/vs_intro.jpg)
### 五、Jetbrains 插件
**主要功能**：和 Chrome 插件功能基本相同，习惯在 Jetbrains 家的 IDE（PyCharm/Intellij/Goland 等）上刷题的读者可以使用该插件。安装使用手册见下方目录。
