Dec 22, 2017 · Given a singly linked list, select a random node from linked list (the probability of picking a node should be 1/N if there are N nodes in list). You are given a random number generator. Below is a Simple Solution 1) Count number of nodes by traversing the list. 2) Traverse the list again and select every node with probability 1/N. Jan 18, 2017 · In a singly-linked list, every element contains some data and a link to the next element. On the other hand, every node in a doubly-linked list contains some data, a link to the next node and a link to the previous node. The elements of a linked list are called the nodes. A node has two fields i.e. data and next.

  19. So, let's implement the simplest one (singly linked list) and the most complex one (circular-doubly linked list) in an old-fashioned way without using the LinkedList class from the Java API library.

  21. A singly linked list with access only from the head would perform worse than what the table shows. Array insertion at the end is Θ (1) if the array is pre-allocated with enough capacity. Otherwise it’s amortized Θ (1) (worst case Θ (n)) if it’s a dynamic array that needs to expand.
  22. In this article, we will learn what is singly linked list and it's implementation using Java. A singly linked list consists of a number of nodes in which each node has a next pointer to the following element. The link of the last node in the list is NULL, which indicates the end of the list.
