This builds upon our previous Odd-Even Printer problem, and introduces a powerful generalization: using modular arithmetic and thread IDs to coordinate thread turns.

🔍 𝐊𝐞𝐲 𝐂𝐨𝐧𝐜𝐞𝐩𝐭𝐬 𝐂𝐨𝐯𝐞𝐫𝐞𝐝:
- How to combine Odd and Even Printer logic into a single class
- When to use while instead of if with wait()
- Why notifyAll() is safer than notify() in real-world scenarios
- Generalizing (current - 1) % totalThreads != threadId to scale to M threads
- A clean and elegant solution using one class for multiple threads

🚀 This video is part of the “Multithreading in Java” series where we take real-world problems and teach interview-level concepts clearly and practically.
