初级代码游戏的专栏介绍与文章目录-CSDN博客

我的github：codetoys，所有代码都将会位于ctfc库中。已经放入库中我会指出在库中的位置。

这些代码大部分以Linux为目标但部分代码是纯C++的，可以在任何平台上使用。

        为了提高并发性，把每个结构改成十个同样的结构是一个可行的办法。

目录

一、set-list的分块版本

二、更基础的set的分块版本

        当然从技术角度，我们程序员一般不应该谈论“十个”，程序员眼里应该只有“一和多”。

        不过由于写成固定个数比较简单而且已经达到较好性能，所以就沿用下来。

一、set-list的分块版本

        这是基于上一篇介绍的set-list结构
