If you want to practice data structure and algorithm programs, you can go through Java coding interview questions. In this post, we will see about Doubly LinkedList implementation in java. We have already seen the implementation of singly linked list. You can consider this as an extension of ...

Shuffling in doubly-linked lists The Java Collections Framework includes a Collections class of utility methods, which is part of the java.util package. This class includes a void shuffle(List<?> list) method that “randomly permutes the specified list using a default source of r...
Design your implementation of the linked list. You can choose to use a singly or doubly linked list.
Note: We can also solve this using the first condition (for the node before del_node) of the second case (Delete the inner node). Doubly Linked List Code in Python, Java, C, and C++ Python Java C C++ import gc # node creation class Node: def __init__(self, data): self.data =...

In this post, we will see how to reverse a doubly linked list using iteration and recursion. Practice this problem 1. Iterative Solution The idea is simple – Traverse the list and swapnextandprevpointers for each node. Finally, updateheadpointer to point to the last node. ...

a linear data structure, in which the elements are not stored at contiguous memory locations. The elements in a linked list are linked using pointers. In simple words, a linked list consists ofnodes where each node contains a data field and a reference(link) to the next node in the list...
Problem Convert a BST to a sorted circular doubly-linked list in-place. Think of the left and right pointers as synonymous to the previous and next pointers in a doubly-linked list. Let's take the following BST as an example, it may help you understand the problem better: ...
