Customer Service Line

A customer service center uses a queue to manage incoming calls. Each customer call is represented by a unique ID. When a call comes in, it is added to the end of the queue. The service agent answers calls in the order they are received. Create a function that simulates this behavior by processing a list of incoming calls and outputting the order in which they are answered. Input format: - The first line contains an integer n (1 ≤ n ≤ 100) - the number of customer calls. - The following n lines each contain a unique call ID. Output format: - Print each call ID in the order they were answered on a new line. Example: Input: 4 123 456 789 101 Output: 123 456 789 101
