Harris Butt 2 months ago Why are you making a cur and per node dynamically Instead you can take two node type pointers in insert-position function… what are their purpose they remain empty after a new node is inserted between them and what happen to the nodes which are present at the place of cur and pre…?? Reply Jaimie 5 months ago This tutorial is rather sloppy.
The range of questions can be from simple questions like finding the length of linked list to very difficult e. Nevertheless, point is that you should be familiar with linked list data structure and must know how to perform basics task in linked list e.
These linked list problems are not only good for coding interviews point of view but also very useful in learning programming. You should try to solve this problem yourselves, before looking at the solution to get the full benefit of them. A linked list is nothing but a collection write a c program of singly linked list nodes, where each node contains a value and pointer to the next node in the list.
This structure allows you to create a chain of nodes which are scattered through different memory areas, which is in stark contrast to the array, where elements always stay in the adjacent and contiguous memory location.
The first node in the linked list is called head while the last node is called the tail. There is also two types of linked list, singly linked and doubly linked list. The singly linked list allows you to traverse in only forward direction, but doubly linked list allows you to traverse in both forward and backward direction.
In order to find an element in linked list, you need to traverse the linked list and compare each node value to the given value, this makes it an O n operation, not ideal when you need to frequently search, but linked list is great for adding and removing nodes from the start and end because you just need to change one link and you don't need to shift elements like array.
I am not sharing solution but you will find the solution of many articles in this blog itself, wherever possible have given links to the solution and at some places I have also given hints to solve the problem by yourself.
How to find middle element of a singly linked list in one pass? If Interviewer says that you cannot loop twice and you just have to use one loop, then you can use the two pointer approach to solving this problem.
In the two pointer approach, you have two pointers, fast and slow.
In each step, the fast pointer moves two nodes, while slow pointer just steps one node. So, when fast pointer will point to the last node i. How to check if linked list contains loop in Java?
How to find the starting node of the loop solution This is another interesting linked list problem which can be solved using the two pointer approach discussed in the first question. This is also known as tortoise and hare algorithm.
Basically, you have two pointers fast and slow and they move with different speed i. If linked list contains cycle then at some point in time, both fast and slow pointer will meet and point to the same node, if this didn't happen and one of the pointer reaches the end of linked list means linked list doesn't contain any loop.
How to reverse a linked list in Java? Some of you may think this is the simplest of linked list problem but when you actually go doing it, you will be stuck and many places. The simplest approach to solving this problem is by using recursion because linked list is a recursive data structure as shown in the solution article.
How to reverse a singly linked list without recursion in Java? How would you remove a node from a doubly linked list? In order to remove a node from the doubly linked list, you need to go through that node and then change the links so that it points to the next node.
Removing nodes from head and tail is easy in linked list but removing a node from the middle of the linked list requires you to travel to the node hence take O n time. If you want to learn more about basic operations on linked list data structure, please read a good book on Data Structure and Algorithms e.
Introduction to Algorithms by Thomas H. Write a Program to convert a binary tree into a doubly linked list? The left and right pointers in nodes of a binary tree will be used as previous and next pointers respectively in converted doubly linked ist.
The order of nodes in the doubly linked list must be same as Inorder of the given Binary Tree.What is the most elegant way to check if the directory a file is going to be written to exists, and if not, create the directory using Python? This type of linked list is known as simple or singly linked list.
A simple linked list can be traversed in only one direction from head to the last node. The last node is checked by the condition. C Program for Bubble Sort on Linked List.
