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,

A hash table (also called a hash table) is a data structure that is directly accessed based on the key value. That is to say, It maps the key value to a location in the table to access records to speed up the search. This ing function is called a
