Answer 1

const mtrix = [
    [1, 0, 2, 14],
    [3, 5, 6, 18],
    [7, 4, 9, 22]
];
 
const rows = mtrix.length;
const cols = mtrix[0].length;
 
let odd = 0, even = 0;  
          
for (let i = 0; i < rows; i++) {  
    for (let j = 0; j < cols; j++) {  
        if (mtrix[i][j] % 2 == 0)  
            even++;  
        else
            odd++;  
    }  
}  
            
console.log("The frequency of odd numbers = " + odd);  
console.log("The frequency of even numbers = " + even);  
 
   
     
     
/*
run:
 
The frequency of odd numbers = 5
The frequency of even numbers = 7
     
*/
