Commonly used string hash functions and Elfhash,aphash and so on, are very simple and effective methods. These functions use bitwise operations to make each character have an effect on the last function value. There are also hash functions represente

Commonly used string hash function and Elfhash,aphash, and so on, are very simple and effective method. These functions use bitwise arithmetic to make each character affect the last function value. There are also hash functions represented by MD5 and

Label:The meaning of hash algorithm is to provide a method of fast access data, it uses an algorithm to establish the correspondence between the key value and the real value, (each real value can have only one key value, but a key value may

Label:Summary of research on hash table and hash functionWith the increasing of information level, the data has been replaced computing as the center of Information Computing, the demand for storage has been increasing the volume of explosive growth

the significance of hash algorithm is to provide a fast access data method, it uses an algorithm to establish the corresponding relationship between the key value and the real value (each True value can have only one key value, but a key value can co

Label:Basic conceptsThe so-called perfect hash function refers to a hash function that has no conflict, that is, to any key1! = Key2 has h (key1)! = h (key2).Set the definition field to X, the range is Y, n=| x|,m=| y|, then there must be m>=n,
