Reverse Linked List Given the head of a singly linked list reverse the list and return the reversed list Example 1 https assets leetcode uploads 2021 02 19 rev1ex1 jpg Input head 1 2 3 4 5 Output 5 4 3 2 1 Example 2 https assets leetcode uploads 2021 02 19 rev1ex2 jpg Input head 1 2 Output In this unit test, we first construct a sample linked list with five nodes. Also, we verify that each node in the linked list contains the correct data value. Then, we call the iterative function to reverse the linked list. Finally, we check the reversed linked list to make sure the data are reversed as expected. 4.

Reverse A Linked List

Reverse A Linked ListReversing a Linked List is an interesting problem in data structure and algorithms. In this tutorial, we’ll be discussing the various algorithms to reverse a Linked List and then implement them using Java. Reverse a Linked List. LinkedList is a data structure which stores the data in a linear way. Though not in a contiguous way . In this tutorial we showed a sample linked list and its reversal Also we discussed two algorithms that can reverse a linked list in linear time
