LeetCode: 206 🚀 | Reverse Linked List | Day 9/30 DSA Challenge 🔁

🚀 Day 9/30 DSA Challenge
In this video, we solve LeetCode 206: Reverse Linked List using an efficient iterative approach in Java.

💡 Problem Statement:
Given the head of a singly linked list, reverse the list and return the reversed list.

🔥 Approach Used (Iterative Method):
We use three pointers:

prev → to store previous node
current → to traverse the list
next → to store next node

👉 Step-by-step:

Store next node
Reverse current node link
Move prev and current forward
Repeat until list ends

⚡ Time Complexity: O(n)
⚡ Space Complexity: O(1) (In-place)
