### **❤️致各位题友的一封信（使用仓库前必读）**
大家刚开始刷题时，会有不知道该从何刷起，也看不懂别人题解的情况
不要着急，这是正常的。
当你刷题一定数量之后，你就会有自己的刷题思维。
知道这个题目属于何种类型，使用什么解题方法。
刷题速度也会大幅提升。
我现在想做的就是尽量把一些基础但很经典的问题细化，理清逻辑。
为后面的师弟师妹提供一丢丢帮助。
毕竟刚开始刷题时，不知道从哪开始和看不懂题解，是很打击自信心的，
我就想着帮助大家尽快度过这段时期，让刷题初期的你对刷题没有那么排斥
所以基地里的题解都尽量用动画模拟，加深大家对题目的理解。往下看吧
另外因为一个人的精力有限，所以基地目前只有 JAVA 代码，欢迎大家贡献其他版本代码。
贡献仓库注意事项
- 提交的代码必须符合编码规范
- 必须经过测试，可以在刷题网站上面 AC
- 符合动画思想
- 可以对代码进行简写，难懂的地方注意添加注释，因为我们的基地主要是为刚刷题的同学服务，所以就尽量让大家容易理解一些。
如果想要贡献代码的大佬可以添加我的微信 [**tan45du_one**](https://cdn.jsdelivr.net/gh/tan45du/tan45du.github.io@master/个人微信.15egrcgqd94w.jpg) 备注贡献仓库即可。
在这里先替所有使用仓库的同学，谢谢各位贡献者啦。
如果老哥觉得仓库很用心的话，麻烦大佬帮忙点个 star ，这也是我们一直更新下去的动力。
感谢支持，该仓库会一直维护，希望对各位有一丢丢帮助，
> 另外我和几位老哥，给刚开始刷题，但是不知道从哪里开始刷的同学，整理了一份 【刷题大纲 】可以先按这个顺序刷，刷完之后应该就能入门，当然该仓库的大部分题解也是来自那个大纲。
>
> 需要的同学可以扫描下方二维码回复【刷题大纲】获取
我把我之前学习算法时，**对我帮助很大的算法书籍，谷歌大神的刷题笔记，面经等整理在了云盘**，需要进阶的同学，可以自己下载，比较适合有一定基础的同学。
> **[下载地址](https://wwr.lanzoux.com/iSGhjox0yne)**
想要手机阅读的大佬，可以来我的[公众号：袁厨的算法小屋](https://cdn.jsdelivr.net/gh/tan45du/test@master/微信图片_20210320152235.wp1ysdbibsw.png)进行阅读，两个平台同步更新，另外想要和题友们一起刷题**的同学可以来我的小屋，**点击**刷题小队**进入，另外群里老哥还会不定期发布内推消息，面经等，需要的可以进一下,不过来的时候**记得备注**，希望这个群能对你们有一丢丢帮助吧，一起加油。
