Скачать или смотреть Solving LeetCode "Two Sum" | Iteration (Brute Force) vs. HashMap Optimization 🚀 | Java Tutorial

In this video, I solve the LeetCode "Two Sum" problem using two different techniques:
🔹 Brute Force (Nested Loops) – Iterating through all pairs to find the solution.
🔹 Optimized HashMap Approach – Using a HashMap to achieve O(n) time complexity.

You'll learn how to efficiently find two indices that add up to a given target. Whether you're a beginner or preparing for coding interviews, this tutorial will help you understand both naive and optimized solutions.

📌 Topics Covered:
✔️ Two Sum problem explanation
✔️ Brute Force (O(n²) approach)
✔️ Optimized HashMap solution (O(n) approach)
✔️ Step-by-step code walkthrough in Java
✔️ Understanding HashMap get() and put() methods
