Find Peak Element in Array - LeetCode 162 - Binary Search Tutorial

Learn how to efficiently find a peak element in an array using Binary Search! ⛰️

In this video, we tackle the "Find Peak Element" problem (LeetCode 162). A peak element is an element that is strictly greater than its neighbors. While a linear scan is easy, we can solve this in O(log N) time complexity by leveraging the properties of Binary Search, even on an unsorted array.

We'll cover:
1. Problem definition and constraints
2. Why Linear Scan is O(N)
3. Intuition for O(log N) solution (Hill Climbing analogy)
4. Step-by-step visualization of the algorithm
5. Complete Python code implementation

Perfect for coding interview preparation and mastering binary search variations.
