Now let's finally delete a node from a linked list. So let's say we have some other function that is finding a node we want to delete and has given us a pointer to exactly the node that we want to delete. We don't even need-- say the head is still globally declared. We don'...

The first node’s “previous” link field contains null to signify the list’s end. Try to think of a doubly-linked list as a pair of singly-linked lists, each interconnecting the same nodes. The diagram in Figure1 shows topForward-referenced and topBackward-referenced singly-linked lists....

Your task is to implement a double linked list. Write a program which performs the following operations: insert x: insert an element with key x into the front of the list. delete x: delete the first element which has the key of x from the list. If there is not such element, you nee...
Given a Binary Tree (Bt), convert it to a Doubly Linked List(DLL). The left and right pointers in nodes are to be used as previous and next pointers respectively in converted DLL. The order of nodes in DLL must be same as Inorder of the given Binary Tree. The first node of Inorde...
