Answer 1

using System;

class Program
{
    static void printLowerTriangular(int[,] matrix) {
        int rows = matrix.GetLength(0);  
        int cols = matrix.GetLength(1);  
          
        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < cols; j++) {
                if (i < j) {
                    Console.Write("0" + " ");
                }
                else {

    static void Main() {
        int[,] matrix = { {1, 2, 3},
                          {4, 5, 6},
                          {7, 8, 9} };
  
        printLowerTriangular(matrix);
    }
