In this video, we revisit the Two Sum problem from LeetCode, but this time, we take it to the next level by solving it in O(n) time complexity using an unordered map (hash map). This method is far more efficient than the brute force solution!
👉 What you'll learn:
How to use an unordered map to optimize your solution
Why this approach reduces the time complexity to O(n)
Step-by-step breakdown of the code in an easy-to-understand way
Whether you're a beginner or prepping for interviews, this video will help you deepen your problem-solving skills! 💡
