My issue

My code

import java.util.Scanner;

public class IPLTicketBooking {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        // Read the number of test cases
        int T = scanner.nextInt();

        // Iterate over the test cases
        for (int i = 0; i < T; i++) {
            // Read the values of N and M
            int N = scanner.nextInt();
            int M = scanner.nextInt();

            // Calculate the number of students who won't be able to book tickets
            int studentsWithoutTickets = 0;
            if (M < N) {
                studentsWithoutTickets = N - M;
            }

            // Print the result
            System.out.println(studentsWithoutTickets);
        }

        scanner.close();
    }
}
