The origin of the "system learning hash Algorithm" in this paper. After seeing the " 11, thoroughly parse hash table algorithm from beginning to end"
Can massive route tables be stored in HASH tables?-HASH search and TRIE tree searchNever! Many people say this, including me.The Linux kernel has long removed the HASH route table, and now only TRIE is left. However, I still want to discuss these
The simple hash is to use the combination of array plus list to achieve, this hash is very simple, but the idea of hash in that.#ifndef _hash_h_#define _hash_h_typedef struct _listnode{struct _listnode *prev;struct _listnode *next;void *data;}

The time efficiency of the list lookup is O (N), and the log2n,b+ tree is log2n by the binary method, but the time efficiency of searching the hash list is O (1).
Design efficient algorithms often need to use the hash list, the constant
