A queue is the most suitable data structure for managing customer service requests. The requests arrive in the order they are submitted, and should be handled in that order, which aligns perfectly with the FIFO principle of a queue.
Key Operations:
- Enqueue (addRequest): Adds a new customer service request to the end of the queue. This simulates a new request being received.
- Dequeue (handleRequest): Removes the customer service request from the front of the queue. This simulates a customer service agent handling a request.
- isEmpty(): Checks if the queue is empty (no requests waiting).
Time Complexity:
- enqueue(): O(1) - Adding to the end of a queue is a constant-time operation.
- dequeue(): O(1) - Removing from the front of a queue is a constant-time operation.
- isEmpty(): O(1) - Checking if a queue is empty is a constant-time operation.
Using a queue ensures that requests are processed fairly and in the order they were received, preventing any requests from being overlooked.
