# 第二章 - 91 天学算法

很多教育机构宣传的 7 天，一个月搞定算法面试的，我大概都了解了下，不怎么靠谱。学习算法这东西，还是要考积累，没有量变是不可能有质变的。还有的人选择看书，这是一个不错的选择。但是很多人选了过时的或者质量差的书，又或者不会去写书中给的练习题，导致效果很差。

基于这几个原因，我组织了一个 91 天刷题活动，通过一个相对比较长的时间（91 天）给出最新的学习路径，并强制大家打卡这种高强度练习来让大家**在 91 天后遇见更好的自己**。详细活动介绍可以点下方链接查看。另外往期的讲义也在下面了，大家可以看看合不合你的口味。

最后送给大家一句话： **坚持下去，会有突然间成长的一天**。
