LeetCode 217: Contains Duplicate - 3 Approaches Explained (Java & Python)| Lean with podcast and Fun

Learn how to solve LeetCode Problem 217, 'Contains Duplicate,' with this in-depth explanation! We break down the problem and explore three distinct algorithmic approaches:

Brute Force: Understand the straightforward, but less efficient, O(n²) solution.
Sorting Approach: Discover how sorting the array can lead to an O(n log n) solution.
Hash Set Approach: Dive into the most efficient O(n) solution using a hash set, including its time and space complexity trade-offs.
This video provides clear conceptual explanations for each method, along with detailed code implementations in both Java and Python for the Hash Set approach. Perfect for anyone preparing for coding interviews or looking to deepen their understanding of data structures and algorithms.
