Coding problem1

Interview was started around morning 10am. Interview panel members were so nice and helpful during the interview. There were 2 Interviewers in meet. One Interviewer was asked questions on problem solving and other was asked on Tech development. I remember only 1 DSA Question.

1. Clone a Linked List with random pointers

Easy

0/40

Asked in companies

You are given a linked list containing 'n' nodes, where every node in the linked list contains two pointers:

(1) ‘next’ which points to the next node in the list

(2) ‘random’ which points to a random node in the list or 'null'.

Your task is to create a 'deep copy' of the given linked list and return its head.

Note:

A 'deep copy' of a linked list means we do not copy the references of the nodes of the original linked list, rather for each node in the original linked list, a new node is created.

Problem approach

step 1: I first applied hashmap to store the next and random pointers. And iterated over a original and cloned the linked list with next and random pointers which are stored.
step 2: Then i gave approach without space. But We need to iterate over original linked list over linked list 3 times. TC -> 3*O(N)
