This post mainly introduces the principle and implementation of the common data structure of hash table. Because the personal level is limited, the article inevitably exists inaccurate or unclear place, hoped that everybody may correct:I.
Common hash Functions The generic hash function library has the following string hashing algorithms that mix addition and one operation. The following algorithms are different in terms of usage and functionality, but can be used as an example to
First, let's take a look at the basic concepts.
A hash table is a table that stores key-value pairs, the reason for not calling it map (the storage of key-value pairs together is usually called map) is that it has the following features: it can map

Hash List Overview
A hash table is a structure in which data is stored in key-value (key-indexed), and we can find its corresponding value as long as we enter the value that we want to find,
