- 3. What is a Queue? What is a Queue? A queue is a linear data structure that follows the FIFO (First In, First Out) principle. Elements are added at the rear and removed from the front of the queue. A queue is a linear data structure that follows the FIFO (First In, First Out) principle. Elements are added at the rear and removed from the front of the queue.
- 4. Queue Operations Queue Operations Common operations on a queue include enqueue (adding an element), dequeue (removing an element), peek (viewing the front element), and checking for empty or full conditions.

- 5. Implementation of Queues Implementation of Queues Queues can be implemented using arrays or linked lists. Each approach has its own advantages and trade-offs in terms of time complexity and space efficiency. Queues can be implemented using arrays or linked lists. Each approach has its own advantages and trade-offs in terms of time complexity and space efficiency.
- 6. Circular Queues Circular Queues A circular queue is a variation that efficiently uses the available space by allowing the rear and front pointers to wrap around the queue. This prevents wastage of space. A circular queue is a variation that efficiently uses the available space by allowing the rear and front pointers to wrap around the queue.

- 7. Priority Queues Priority Queues A priority queue is an abstract data type that operates similar to a regular queue, but each element has a priority associated with it. Elements with higher priority are dequeued first. A priority queue is an abstract data type that operates similar to a regular queue, but each element has a priority associated with it.
