How to Find the Middle of a Linked List in $O(N)$ Time! (LeetCode 876)
🚀 Welcome back to DailyCoding! In today's video, we are tackling LeetCode 876: Middle of the Linked List. This is a classic interview problem that perfectly demonstrates the power of the Two-Pointer (Tortoise and Hare) technique.
By the end of this video, you'll understand how to find the middle node of any singly linked list in a single pass with O(N) time complexity and O(1) space complexity!

💻 Code Snippet (Python/Java/C++):
// Fast and Slow Pointer logic shown in the video:
// ListNode slow = head, fast = head;
// while (fast != null && fast.next != null) {
// slow = slow.next;
// fast = fast.next.next;
// }
// return slow;
