WebBy Reversing the List: This method takes O (n) time complexity and O (1) extra space. Approach of this method is to find the middle element of linked list,then take second half list and reverse it,compare this with first half of list if they become equal it means List is pallindrome otherwise not. WebJul 8, 2024 · Algorithms to Check Linked List is Palindrome or Not 1. Using Stacks. In this algorithm, we use a stack of list elements. There are three operations needed to be formed to implement our algorithm. Iterate through all the elements in the given list from head pointer to the tail and push every element to the stack as we traverse.
WebDoubly Linked Lists A doubly linked list is a list that contains links to next and previous nodes. Unlike singly linked lists where traversal is only one way, doubly linked lists allow traversals in both ways. A generic doubly linked list node can be designed as: typedef struct node { void* data; struct node* next; struct node* prev; } node; WebDOUBLY LINKED LIST TO CHECK IF A STRING IS PALINDROME A string is accepted as input from the user. The characters in the string are inserted as nodes into the doubly linked list. Two pointers lptr and rptr are used to point to the beginning and end of the string respectively. The list is traversed from left to right using lptr
