Скачать или смотреть Day 3 | Reverse an Array | Brute Force vs Optimized | 100 Days Coding Challenge (Java)

Day 3 of my 100 Days of Problem Solving Challenge 🚀
In this video, I’ll teach you how to Reverse an Array using both:
✅ Brute Force approach (extra array)
✅ Optimized approach (two-pointer in-place swap)

We’ll solve it step by step in Java, discuss time complexity, and run examples. Perfect for coding interviews & DSA prep!

🔹 Problem Statement: Given an array, reverse its elements.
Example: Input = [1, 2, 3, 4, 5] → Output = [5, 4, 3, 2, 1].
