define hash function

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

Search Algorithm ---- hash tableThe hash method is different from sequential search, binary search, binary sorting tree, and B-tree search. It uses direct addressing technology instead of keyword comparison. Under ideal conditions, you can find the

1. Basic Concepts a hash table, also known as a hash table, is a data structure that is accessed directly from a key value. That is, it accesses records by mapping key code values to a location in the table to speed up lookups. This mapping function

1. Basic Concepts Hash list (hash table. Also called a hash table). is a data structure that is directly visited based on key value.That is, it visits records by mapping key code values to a location in the table. To speed up the search.This mapping
