Linked List


Circular linked list last node point to the first node of linked list. The single linked list last node point to null value which uses to identify the end of linked list. But, the circular linked list tail node point to the head node. A circularly linked list node looks exactly the same as a linear singly linked list.Write a program to implement circular linked list. Once the item moved to tail, it overrides the head items

Write a program to find last Nth node from singly linked list using single iteration. Linked list do not use index and uses only reference to next item. Algorithm Explanation Take two pointers for finding the last Nth node. Slow pointer and fast pointer initialize with head pointer.Move fast pointer to Nth node.Iterate both slow pointer and fast pointer till end of the linked list. When the fast pointer move to end of linked list, the slow pointer point to last Nth nodeReturn the element to display the data Source Code package com.dsacode.DataStructre.linkedlist; class Node{ public int val; public Node…

Doubly linked list is a linked data structure that consists of a set of sequentially linked nodes. Each node contains two links (references to the previous and to the next node) and data. The links help to iterate the node forward and backward.Write a program to implement doubly ended linked list with all the operations.

Insertion sort is a sorting algorithm uses to sort items in the array or linked list. It can sort the elements in ascending order or descending order. Insertion sort is a simple sorting algorithm. It works efficiently for small data sets. Insertion sort builds the sorted array. It is best suitable for nearly sorted arrays and a small set of elements. Write a program to sort the elements in the linked list using insertion sort
