Write a Java program that takes a 2D array of size 2x3 and returns its transpose.

1  2  3  
4  5  6

Output:

1  4  
2  5  
3  6

public class Main {
    public static void main(String[] args) {
        int[][] matrix = {
            {1, 2, 3},
            {4, 5, 6}
        };
        
        int[][] transpose = new int[3][2];
        
        for (int i = 0; i < matrix.length; i++) {
            for (int j = 0; j < matrix[i].length; j++) {
                transpose[j][i] = matrix[i][j];
            }
        }
        
        // Print Transpose
        for (int i = 0; i < transpose.length; i++) {
            for (int j = 0; j < transpose[i].length; j++) {
                System.out.print(transpose[i][j] + " ");
            }
            System.out.println();
        }
    }
}
