Can you solve this real interview question? Linked List Cycle II - Given the head of a linked list, return the node where the cycle begins. If there is no cycle, return null. There is a cycle in a linked list if there is some node in the list that can be reached again by continuously following the next pointer. Internally, pos is used to denote the index of the node that tail's next pointer is

Today, we will be solving some of the most common linked list problems on LeetCode. The idea is to get you familiar with the concept of linked lists and how to solve problems on them. The problems we will be tackling will cut across different types of linked lists, with difficulty ranging from easy to hard, all approached step by step

a is a reference to ListNode1.There are two references to ListNode2 the one stored in ListNode1, referenced as a.next, and one in b.. Think of these references as arrows. When you make the assignment b None, you simply removing the arrow from b to ListNode2 and replacing it with an arrow from b to None.This has no effect on the arrow from ListNode1 to ListNode2.

When you access a property, you use dot notation. Right? Something like Object.property. So in the case of Linked Lists, its Node.next. And the value of next is just another Node. Node1.next Node2, Node2.next Node3 When Node.next is null, it just means you have reached the end of the linked list

Get Length of a Linked List in Python. Step-by-step Approach Initialize a size counter with 0. Check if the head is not None. If the head is None, return 0 as the linked list is empty. Traverse the linked list using a while loop until current_node becomes None. In each iteration, increment the size by 1.

Among these, the linked list stands out for its flexibility and variety of use cases. Recently, I embarked on a journey to deepen my grasp of linked lists by solving medium-level problems on LeetCode.
