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 trend,
We know thatDirect addressing)To access any element in the array within the O (1) time. Therefore, if the bucket permits, an array can be provided to reserve a location for each possible keyword, and direct addressing technology can be applied.
Hash
We know that any element in an array can be accessed within an O (1) time by direct addressing via an array (directly addressing). Therefore, if the storage space allows, you can provide an array, for each possible keyword to maintain a location,
Hash
Hash, the general translation to do "hash", there is a direct transliteration of "hash", is the arbitrary length of the input (also known as pre-mapping, pre-image), through the hash algorithm, transformed into a fixed-length output,
