Key components of separate chaining

Now that we know what separate chaining is let us look at the structure of a separate chaining implementation of a hash table using a doubly linked list. The hash table is just an encapsulation around an array of linked lists that stores key-value pairs. Different pieces have to be put together to create a hash table. Let us look at all the components and functions needed to implement such a hash table.

Record

Each linked list node stores the key-value pair that represents the mapping in the separate chaining implementation of a hash table. A record is a data structure encapsulating this key-value pair, making it easy to use and operate. Each node in the linked list holds data in this format.
