For example, the number ... Linked lists can also be palindromes if they have the same order of elements when traversed forwards and backward.

Linked List is a palindrome. The time complexity of the above solution is O (n), where n is the total number of nodes in the linked list. The auxiliary space required by the solution is O (n) for the stack container. We can determine whether a linked list is a palindrome in linear time and with constant space. Problem description : Write a function to determine if a singly linked list is a palindrome. Input : A linked list Output : Boolean (true or false) Approach 1: Reverse and compare the linked lists. Logic : Create a new copy of the linked list. Reverse the newly created linked list. Compare the original linked list with the reversed linked list. Given a doubly-linked list of characters, write a function that returns true if the given doubly linked list is a palindrome, else false.
