Answer 1

using System;

class Program
{
    static void Main() {
        int[,] m = {     
                       {1, 0, 2},  
                       {3, 5, 6},  
                       {7, 4, 1}  
                   };    

        int rows = m.GetLength(0);  
        int cols = m.GetLength(1);  
          
        int odd = 0, even = 0;  
        
        for (int i = 0; i < rows; i++){  
            for (int j = 0; j < cols; j++){  
                if(m[i,j] % 2 == 0)  
                    even++;  
                else  
                    odd++;  
            }  
        }  
          
        Console.WriteLine("The frequency of odd numbers = " + odd);  
        Console.WriteLine("The frequency of even numbers = " + even);  
    }
}




/*
run:
  
The frequency of odd numbers = 5
The frequency of even numbers = 4
  
*/
