说明：  最近简单的学习了一些常用的数据处理算法，在这里我简单的做一个系列笔记和大家一起学习国内外一些常见的数据处理算法，之前也做了java的实现，但是由于考虑到性能问题最终还是采用的C语言实现
(Recently, I have simply learned some common data processing algorithms. Here, I will make a series of notes and learn some common data processing algorithms at home and abroad with you. Before that, I also implemented Java. However, due to the consideration of performance problems, I finally implemented it in C language.)
