In this LeetCode Explained video, we're tackling problem 342, Power of Four. Learn how to solve this popular coding challenge and why the follow-up question "Can you solve it without loops or recursion?" is so important. We'll first cover the straightforward iterative approach by repeatedly dividing by four. Then, we'll unlock the elegant O(1) constant-time solution using a clever combination of bit manipulation (to check if it's a power of two) and a unique mathematical property involving divisibility by three. This is a must-know trick for your coding arsenal!
