What is the best data structure for implementing a queue?

The best data structure for implementing a queue is typically a linked list or an array. Each has its pros and cons.

Can you explain the advantages of using a linked list over an array?

Sure! A linked list allows for dynamic memory allocation, which means it can grow and shrink as needed, while an array has a fixed size.

What about the performance in terms of time complexity?

For both linked lists and arrays, enqueue and dequeue operations can be O(1) for linked lists, while arrays can be O(n) if resizing is needed.

Are there any specific scenarios where one is preferred over the other?

Yes, if you need a fixed-size queue, an array might be simpler. For dynamic queues, a linked list is usually better.
