Given a Doubly Linked List, the task is to reverse the given Doubly Linked List....

Following is a typical recursive implementation of QuickSort for arrays. The implementation uses last element as pivot....
Introduction to Singly linked list : A singly linked list is a set of nodes where each node has two fields ‘data’ and ‘link’. The ‘data’ field stores actual piece of information and ‘link’ field is used to point to next node. Basically the ‘link’ field stores the address of the next node....
A doubly linked list is a more complex data structure than a singly linked list, but it offers several advantages. The main advantage of a doubly linked list is that it allows for efficient traversal of the list in both directions. This is because each node in the list contains a pointer to the previous node and a pointer to the next node. This allows for quick and easy insertion and deletion of nodes from the list, as well as efficient traversal of the list in both directions....
Given a Binary Tree (BT), convert it to a Doubly Linked List(DLL) In-Place. 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 Inorder traversal (left most node in BT) must be head node of the DLL....

Given a doubly linked list, rotate the linked list counter-clockwise by N nodes. Here N is a given positive integer and is smaller than the count of nodes in linked list....
Given a Binary Tree, extract all leaves of it in a Doubly Linked List (DLL). Note that the DLL need to be created in-place. Assume that the node structure of DLL and Binary Tree is same, only the meaning of left and right pointers are different. In DLL, left means previous pointer, and right means next pointer....
Given a doubly-linked list containing N nodes, where each node is at most K away from its target position in the list, the task is to sort the given doubly linked list....
Given K sorted doubly linked list. The task is to merge all sorted doubly linked list in single sorted doubly linked list means final list must be sorted.Examples:...
Given a 2D matrix, the task is to convert it into a doubly-linked list with four pointers that are next, previous, up, and down, each node of this list should be connected to its next, previous, up, and down nodes.Examples:...
