💡 LeetCode 217: Contains Duplicate | JavaScript Solution Explained| Brute Force & Optimized Approach

🚀 LeetCode 217: Contains Duplicate (JavaScript Solution | Brute Force + Optimized Approach)
In this video, we solve the LeetCode 217: Contains Duplicate problem using JavaScript. We’ll go through two different approaches:

1️⃣ Brute Force Approach (O(n²)) – Simple, but inefficient for large inputs.
2️⃣ Optimized Approach Using a Set (O(n)) – A faster and more elegant solution.

This problem is frequently asked in coding interviews, and this video will help you understand different problem-solving techniques in JavaScript.

🔥 What You’ll Learn in This Video
✔️ How to detect duplicates in an array efficiently
✔️ The difference between O(n²) and O(n) solutions
✔️ How JavaScript’s Set data structure improves performance
✔️ Best practices for solving LeetCode problems
