5M | Java | Check If a Number Is Odd or Even Using Bitwise AND | Simple Explanation with Code
Want to know a fast and efficient way to check if a number is odd or even? 🤔
In this video, I’ll show you how to use the bitwise AND (&) operation to determine whether a number is odd or even — without using any modulus (%) operator!
✨ Concept Covered:
✔️ How binary representation helps
✔️ Why num & 1 gives the result
✔️ Simple C++/Java/Python code example
✔️ Works for both positive and negative numbers
if (num & 1 == 0) → Even
else → Odd
📌 Why use this?
✅ Faster than modulus
✅ Useful in competitive coding
✅ Great for understanding low-level number manipulation
