如果__n不为nullptr,说明之前已有同样元素存在。 如果hash表元素是int,那么会生成一个为其特化的hashtable,其hash值不需要计算,而是直接用value % 11得到其__bkt值,进而插入hash表。
I just wanted a simple and straightforward hash table implementation that I could drop into my own C-based projects on whatever platform.I haven't implemented one of these before, so it may be super naive, but it does appear to work pretty well.NOTE...
i have no doubts though that it is of highest quality too. this hash table implementation is currently hardwired to be used with string keys. it would be trivial to support other types too, but the more generic, the more messy the API becomes. see test.c for usage examples....

一致性哈希算法在 1997 年由麻省理工学院提出,是一种特殊的哈希算法,在移除或者添加一个服务器时,能够尽可能小地改变已存在的服务请求与处理请求服务器之间的映射关系; 一致性哈希解决了简单哈希算法在分布式哈希表(Distributed Hash Table,DHT)中存在的动态伸缩等问题; ...
一致性哈希解决了简单哈希算法在分布式哈希表(Distributed Hash Table,DHT)中存在的动态伸缩等问题; 一致性hash算法本质上也是一种取模算法; 不过,不同于上边按服务器数量取模,一致性hash是对固定值2^32取模; IPv4的地址是4组8位2进制数组成,所以用2^32可以保证每个IP地址会有唯一的映射; ...

最近在学习CMU的15-445 DB课程,在做Project1的Extendible Hash Table的时候,由于是先看了课程,过了一个多星期才做的Lab,对extendible hash table只能说是知道大体的意思,并没有透彻的了解它,尤其是bucket指针和数据重分配这一部分,涉及到比较tricky的位运算,在一知半解的情况下实现它,完全没办法找到对应的bug,Con...
