🚀 Today’s GeeksforGeeks Problem of the Day (GFG POTD) is a HARD Data Structures question that is frequently asked in coding interviews!
🧠 Problem: Implement K Queues in a Single Array
We are given n slots and need to efficiently manage k independent queues inside just one array — while supporting:
✔️ enqueue(x, i)
✔️ dequeue(i)
✔️ isEmpty(i)
✔️ isFull()
And the best part? We must achieve O(1) time complexity for all operations 😮
💡 What You’ll Learn in This Video
✅ How to manage multiple queues using a single array
✅ Smart use of next array + free list
✅ Avoiding overflow while sharing memory
✅ Queue implementation trick asked in product-based companies
✅ Step-by-step dry run for full clarity
This problem strengthens your understanding of:
Data Structures
Queue Design
Memory Optimization
Interview Problem Solving
🏆 Why This Problem is Important
This is a classic space-optimized data structure design problem that tests:
✔️ Pointer/index management
✔️ Efficient memory usage
✔️ Real interview-level logic
