Bits are the foundation of how computers work. Every number, every character, every pixel on your screen is stored as bits. When you understand how to manipulate bits directly, you unlock solutions that are both faster and more memory-efficient than standard approaches.
In this section, I'll show you how to work with bits using bitwise operators. You'll learn how to check, set, clear, and toggle individual bits. You'll also discover clever tricks that solve problems in ways loops and arrays cannot match.
By the end, you'll recognize when a problem calls for bit manipulation and you'll know exactly how to apply it.
