WebA linked list is a linear data structure where each element is a separate object. Linked list elements are not stored at contiguous location; the elements are linked using pointers. Each node of a list is made up of two items - the data and a reference to the next node. The last node has a reference to null. The entry point into a linked list is called the head of the list.

WebPractice this problem. 1. Linear time solution using extra space. To clone a linked list with random pointers, maintain a hash table for storing the mappings from a linked list node to its clone. We create a new node with the same data for each node in the original linked list and recursively set its next pointers.
