Hoisting in JavaScript : Hot topic for Interview.LinkedList is a data structure which stores the data in a linear way. In this tutorial, we’ll be discussing the various algorithms to reverse a Linked List and then implement them using Java. How everything is Object in JavaScript? Reversing a Linked List is an interesting problem in data structure and algorithms.Part 5 - Find nth last element in singly linked list Let’s catch up in next article with more interesting questions on Linked List, happy reading. Most of the code is same as used in previous articles except that I have introduced a new method called reverseList(), which is responsible for reversing the given list. for(let i=array.length -1 i>=0 i-) var ll = new LinkedList() // adding more elements to the list ll.add(10) ll.add(20) ll.add(30) ll.add(40) ll.add(50) // returns 10 20 30 40 50 ll.printList() ll.reverseList() ll.printList()
Then you need to return the previous node, which. The stopping condition happens when the current node is null. If it would have been array and the interviewer expectation is to just to print the array elements in reverse order, then you could have just ran a loop from the back of the array and print the elements like below. If you look at the table I made, you may notice that in order to reverse the list all you need to do is make the current node to point to the previous node during each recursive call, then move to the next node. This is one of the very common question asked in most of the interviews. We will start with a variable current which will initially point to the head of the Linked List and a variable previous which will point to the previous node that we have processed initially previous will point to null.
