217. Contains Duplicate | Leetcode Unlocked - Python

In this video, we solve LeetCode 217: Contains Duplicate, a foundational problem for anyone preparing for coding interviews. We explore two distinct approaches to detect if an integer array contains any repetitions: the Sorting method (O(N log N)) and the optimal Hash Set approach (O(N)). We break down the Time and Space complexity trade-offs for each solution to help you understand when to use which. While the visual explanation uses Python, full code solutions are provided for Java, C++, and JavaScript. This is the perfect tutorial to master Arrays and Hash Sets! 🧋 Support the channel!
