# 即学即练|基础数据结构篇:复习卡 & 算法题特训
你好,我是微扰君。
到目前为止我们已经学习了课程基础部分的4章内容包括基础数据结构篇、基础算法思想篇以及操作系统和计算机网络这两门非常重要的计算机基础课中会用到的基础算法。不知道你掌握的如何啦
我常在课程里提到只有掌握优秀算法的精髓才能根据实际的workload选择合适的算法但如果缺少足够的练习我们在实际写的时候可能还是会遗漏一些值得考虑的细节而长期不间断的算法训练能磨练我们的思维能力。上一节课也分享了我自己刷算法题的方法。
春节期间我们就来4期特别策划我会带你复习这四大章的要点内容把每篇文章的要点都梳理出来供你快速回顾内容。
另外我也整理了这4章每个核心知识点对应的必知必会的18道LeetCode练习题供你练手复习巩固。你可以每天花一点时间来完成测验。测验完成后如果发现自己哪里还不太明白可以点击要点卡可以直接跳转到你最需要复习的那篇。有针对性地复习。
