WebThese functions use bitwise operations to make each character have an effect on the last function value. There are also hash functions represented by MD5 and SHA1, which are almost impossible to find collisions with. Common string hash functions are bkdrhash,aphash,djbhash,jshash,rshash,sdbmhash,pjwhash,elfhash and so on. Web因此，在编写代码之前，首先需要根据所要处理的数据，选择合适的hash函数和冲突处理办法。开放定址需要空闲存储单元，所需要的表比实际容量大，而且容易产生二次聚集发生新冲突。链地址使用链表存储关键字，可以随时插入新数据，数据量大小不受限制。
