While a singly linked list consists of nodes with links from the one node to the next, a doubly linked list also has a link to the node before it. These previous links, along with the added tail property, allow you to iterate backward through the list as easily as you could iterate forward through the singly linked list.


I wrote a simple chain (nodes) on the example of Baku city metro of 1967 model.
