**************************************************
In this video, I explain how to solve the "Power of Two" problem from LeetCode using an optimized bit manipulation approach in constant time O(1). We dive deep into the logic behind the bitwise operations and how they help us determine if a given number is a power of two efficiently.

🔍 What you’ll learn in this video:
✅ Understanding the problem statement of "Power of Two"
✅ Why bit manipulation is the best approach for this problem
✅ How the expression (n & (n - 1)) == 0 works
✅ Complete Java code implementation with examples

Just check if 2^30 is divisible by n if n > 0. Works with any powers of prime numbers, and no need for support of bitwise operations in the programming language.
