Train Scheduling

In a train scheduling system, trains arrive and depart at specific intervals. Given a list of arrival and departure times, determine the order in which the trains will leave the station based on their scheduled departure times. The list is limited to 100 trains. Input Format: - An integer N (1 ≤ N ≤ 100) that specifies the number of trains. - For each train, two integers A (arrival time) and D (departure time) (1 ≤ A < D ≤ 1000). Output Format: - Output the departure times in ascending order, separated by spaces. Example: Input: 3 10 20 5 15 15 25 Output: 20 25
