In this representation, each node contains two pointers, one pointing to its parent (null in the case of root node) and the other pointing to its child node (null in the case of leaf nodes).

Does each node in a doubly linked list contain a link to the previous as well as the next node?
Yes, each node in a doubly linked list contain a link to the previous as well as the next node. That is the definition of the doubly linked list.
what are the differences between singly link list and doubly link list?
singly linked list stores only the address of next node while doubly linked list stores the address of previous node and next node and hence it is called doubly linked list. In singly linked list only forward traversing is possible while in doubly linked list forward and backward traversal is possible.
Why you use doubly link list?
In a doubly linked list, you can iterate backwards as easily as forwards, as each element contains links to both the prior and the following element. You can also insert or delete an element without needing to iterate and remember the prior element's link. This comes at a cost. You are adding storage to each element for the second link, and you are adding processing overhead to the insert and delete operation. You have to determine the tradeoff.
How do you overcome drawbacks of linked list?
Overcoming the "drawbacks" of a linked list requires knowing what drawback is at stack. If you need to iterate backwards as well as forwards, then you could create a doubly linked list. If you need to search for elements quickly, then you could implement a binary tree. If you have a static size, then you could implement an array. It's all a matter of tradeoff, and of what your particular issue is... Its badsector... According to my self disadvantage of link list that searching in link list is sequential if you compare it with arrays its very slow. Because in link list we have to search every node for that. if any one uses binary tree that is in some cases more faster than arrays.
What is the advantage of doubly linked list over Doubly linked list?
A doubly linked list can be traversed in both directions (forward and backward). A singly linked list can only be traversed in one direction. A node on a doubly linked list may be deleted with little trouble, since we have pointers to the previous and next nodes. A node on a singly linked list cannot be removed unless we have the pointer to its predecessor. On the flip side however, a doubly linked list needs more operations while inserting or deleting and it needs more space (to store the extra pointer).
Convert single linked list to double linked list?
You copy a singly linked list into a doubly linked list by iterating over the singly linked list and, for each element, calling the doubly linked list insert function.
What is the difference between doubly linked list and circular linked list?
A doubly linked list allows traversal in both directions (forward and backward) by having each node point to both its next and previous nodes. A circular linked list is a type of linked list where the last node points back to the first node, forming a circular structure. This allows continuous traversal through the elements without a definitive end.

How tree can be represented using linked list?
A tree is a linked list. Well, sort of... An ordinary linked list has one forward node pointer within each node, while a tree has more than one. Often, in a tree, there is a relationship between nodes, such as an ordering based on which sub-node pointer the current node is a child of.
Which operation is perform more efficiently by doubly linked list than by single linked list?
zsd
What is a singly linked linear list?
A singly linked list is a linked list which only provides links in "one direction". Using a metaphor, a singly linked list is a one way street, while a doubly linked list is a two way street. Once you move forward in a singly linked list, there is no way to go backwards unless you kept your reference/pointer from before. A singly linked list would look like this: start ----> node1---->node2---->node3 ----> NULL You will see that node2 only has a link forward to node3 - it does not have a link backwards to node1, even though node1 has a link forwards to node2. To prevent us from permanently losing access to portions of the linked list, we generally keep a reference/pointer to "start". A doubly linked list would have twice the number of pointers/references as a singly linked list - making it very inefficient to store small datatypes. On the other hand, it would be possible to move both forwards and backwards with a doubly linked list because you have links pointing both forwards and backwards.
Why you used link list in binary tree?
Linked list was introduced to reduce the space wastage done by array & also to make easier the insertion and deletion of elements from a list. A binary tree contains nodes of elements where insertion,deletion & searching is frequently done. So to make these operations easier linked list is used.
