What is a two way list?
A two way list is a linear collection of data elements, called nodes, where each node N is divided into three parts:- information field, Forward link- which points to the next node and Backward link-which points to the previous node.
Why Two Way List is important?
The importance of a two way list is that, a two way list and a circular header list may be combined into a two way circular header list as the figure below. The list is circular because the two end nodes point back to the header node.
