Binary Exponentiation in Java | Fast Power Algorithm Explained (O(log n))

In this video, we build the Binary Exponentiation (Fast Power) algorithm in Java from scratch. Instead of calculating powers using a brute force O(n) approach, we reduce the time complexity to O(log n) using divide and conquer. We cover: Brute Force Power Method (O(n)) Recursive Fast Power (O(log n)) Iterative Binary Exponentiation (Bit Manipulation) Time Complexity Analysis Step-by-step Whiteboard Explanation This concept is extremely important for: Data Structures & Algorithms interviews Competitive Programming GATE / Coding Interviews Understanding divide and conquer patterns Once you understand this technique, you’ll start seeing it everywhere — from modular exponentiation to matrix exponentiation. Java Implementation included.
