In this LeetCode Explained video, we're tackling problem 89: Gray Code. We start by demystifying what a Gray Code sequence is and walk through a simple example to make sure the concept is crystal clear.
We explore two powerful methods to solve the problem. First, we cover the intuitive "Reflect and Prefix" method, a constructive approach where we build the solution for n using the solution for n-1. After that, we dive into a clever mathematical trick using bit manipulation (i XOR (i 1)) for a super concise and efficient solution. We'll implement these approaches in Python and provide the final code in Java, C++, and JavaScript, along with a full analysis of the time and space complexity.
Perfect for coding interview preparation and improving problem-solving skills.
