Reversing a Linked List is an interesting problem in data structure and algorithms. In this tutorial, we’ll be discussing the various algorithms to reverse aLinked Listand then implement them using Java. Reverse a Linked List LinkedList is a data structure which stores the data in a linear wa...
Problem link: Explore - LeetCodeleetcode.com/explore/interview/card/top-interview-questions-easy/93/linked-list/560/ Solutions: 1. Iterative method: The idea of this method is just to reverse the direction of the link one by one. And because you are reversing the direction, in order to...

Problem LeetCode Reverse a singly linked list. Example: Input:1->2->3->4->5->NULL Output:5->4->3->2->1->NULL Follow up: A linked list can be reversed either iteratively or recursively. Could you implement both? 问题 力扣
I recently attempted to solve LeetCode problem141, Linked List Cycle: Givenhead, the head of a linked list, determine if the linked list has a cycle in it. There is a cycle in a linked list if there is some node in the list that can be reached again by continuously following thenext...
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. ...
