里面所有项目都很有价值，
特别是从上贴中淘到3个不错的站点，涉及C语言数据结构算法
-----------------------------------------------
C算法笔记，把所有经典算法写一遍
Learn-Algorithms https://github.com/nonstriater/Learn-Algorithms
-----------------------------------------------
TheAlogrithms/C https://github.com/TheAlgorithms/C
Collection of various algorithms in mathematics, machine learning, computer science, physics, etc implemented in C for educational purposes.
------------------------------------------------
PTA C语言编程，数据结构算法练习 C语言题解。全部用C语言写，追求代码高效简洁，相当不错 ，可以在线练习，类似leetcode https://pintia.cn/problem-sets?tab=0
