public class Main {
    public static void main(String[] args) {
        int[][] arr = {
            {5, 7, 9},
            {4, 6, 8},
            {1, 2, 3}
        };
        
        int searchElement = 6;
        boolean found = false;
        
        for (int i = 0; i < arr.length; i++) {
            for (int j = 0; j < arr[i].length; j++) {
                if (arr[i][j] == searchElement) {
                    System.out.println("Element " + searchElement + " found at position: [" + i + "][" + j + "]");
                    found = true;
                    break;
