Today, we'll talk about Linked List for SDE Interview Preparation.
So, a Linked list is a linear data structure, in which the elements are not stored at contiguous memory locations.
There are numerous concepts in the linked list, like reversing a linked list, detecting a loop in a linked list, and much more.
Let's start with Reversing a linked list. To Understand the concept: https://bit.ly/3wLWKP5
Practice with the problem: Given a linked list of N nodes. The task is to reverse this list.
