How to find the frequency of odd and even numbers in a given matrix with TypeScript

Answer 1

const mtrix : number[][] = [
    [1, 0, 2, 15],
    [3, 5, 6, 20],
    [7, 4, 9, 70]
];
 
const rows : number = mtrix.length;
const cols : number = mtrix[0].length;
 
let odd = 0, even = 0;  
          
for (let i : number = 0; i < rows; i++) {  
    for (let j : number = 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 = 6" 
"The frequency of even numbers = 6" 
     
*/
