Link list ADT

What is linked list?

Linked List consists of a sequence of nodes. These nodes are made-up of the following:

• A Data Field for housing the data item

• One or Two Reference/s for pointing at other node/s i.e. pointing to the next/previous node/s.

In this data structure, the nodes are allowed to be inserted and removed at any point in the list in constant time, however random access in not possible.
