You are creating a ticketing program for a small movie theater. The seats are represented using a 2-dimensional array.

Question

import java.util.Scanner;

public class Program {

public static void main(String[] args) {
int[][] seats = {
{0, 0, 0, 1, 1, 1, 0, 0, 1, 1},
{1, 1, 0, 1, 0, 1, 1, 0, 0, 0},
{1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
{0, 0, 0, 1, 1, 1, 1, 0, 0, 0},
{0, 1, 1, 1, 0, 0, 0, 1, 1, 1}
};
Scanner sc = new Scanner(System.in);
int row = sc.nextInt();
int col = sc.nextInt();

if (row < 1 || row > seats.length || col < 1 || col > seats[0].length) {
System.out.println("Invalid seat position");
} else {

if (seats[row - 1][col - 1] == 0) {
System.out.println("Sold");
} else {
System.out.println("Free");
}
}

sc.close();
This is my code it passing the 3 test cases but giving error for two
