专门为刚开始刷题的同学准备的算法基地

立志用动画将晦涩难懂的算法描述的通俗易懂。

热烈欢迎你的批评指正，但是不接受骂人。感谢支持。

如果阅读时，发现错误，或者动画不可以显示的问题可以添加我 微信好友  [tan45du_one](https://raw.githubusercontent.com/tan45du/tan45du.github.io/master/个人微信.15egrcgqd94w.jpg) ，备注 **github  + 题目 + 问题**

该仓库会一直维护。

另外希望手机阅读的同学可以来我的 **公众号：袁厨的算法小屋** 两个平台同步，想要和题友一起刷题，互相监督的同学，可以在我的小屋点击**刷题小队**进入。
