You must use linked lists in your pseudocode, as discussed in class, and C-program. In this tutorial, we create a linked list and insert a new node at the beginning/head of linked list. Make the link part of the new node pointing to the existing first node of the list. The program should swap two nodes in linked list without swapping their data. Given a linked list, check if it is a palindrome or not. Data structure used: A doubly linked list where each node contains a data part, say data and two link parts say prev (to store the address of immediate previous node) and say . Pseudocode for removing a node of a linked list. There are the following steps which need to be followed in order to inser a new node in the list at beginning. Below is the final list after swapping. Linked list problems are a nice combination of algorithms and pointer manipulation. Lastly we will write a C++Program to implement this Queue using Singly Linked List. We first thought of creating a separate blog for C & C++ related posts, but because of the maintenance issue, we finally decided to merge it to the main blog. @jxh if the linked list has 3 nodes, lets say it has data 1, 2, and 3, and the *p is the head pointer, . Then list1 is set to *pNext, i.e. Step by step descriptive logic to swap two nodes in a singly linked list. The only way to implement a stack is using a linked list. Pseudocode Merge_Sort(head_reference) STEP 1: If head is NULL or there is only one element in the Linked List then return the Linked List STEP 2: Divide the linked list into two equal halves.Split_Linked_List(head, &first_half, &second_half); STEP 3: Sort the two . Just type following details and we will send you a link to reset your password. Based on our understanding of partitioning in Quicksort, we will now try to write an algorithm for it, which is as follows. Implementation of Stack using Linked List. For example if the given Linked List is 4->20->15->10->5 and we add a node 8 at the end, then the Linked List becomes 4->20->15->10->5->8.
