Introduction to the Hash Construction method of Digital keywords

Today, what the editor shares with you is the introduction of the hash construction method of digital keywords. I believe that many people do not know much about it. In order to make you understand better, I have summarized the following contents for you. Let's look down together. I'm sure you'll get something.

The hash construction methods of numeric keywords are as follows: 1, direct address method, syntax is "h (key) = a x key + b"; 2, except residue method, syntax is "h (key) = key mod p"; 3, numerical analysis, syntax is "h (key) = atoi (key + 7)".

A symbol table (SymbolTable) is a collection of Name-Attribute pairs. The core operation of a symbol table is to find, insert and delete.

Hash Construction of Digital keywords

Direct addressing method

H (key) = a x key + b (a, b are constants)

Method of division and residue

H (key) = key mod p

Digital analysis method

H (key) = atoi (key + 7) this is the end of the introduction of hash construction methods for digital keywords. I hope the above content can be used as a reference for everyone. If you like this article, you might as well share it for more people to see.
