矩阵中偶数和奇数频率的Javascript程序

给定一个 m*n 阶矩阵，那么任务是找到矩阵中偶数和奇数的频率
例子：

Input : m = 3, n = 3
        { 1, 2, 3 }, 
        { 4, 5, 6 }, 
        { 7, 8, 9 }
Output : Frequency of odd number =  5 
         Frequency of even number = 4


Input :   m = 3, n = 3
         { 10, 11, 12 },
         { 13, 14, 15 },
         { 16, 17, 18 }
Output : Frequency of odd number  =  4 
         Frequency of even number  = 5

Javascript

// Java Script Program to Find the frequency
// of even and odd numbers in a matrix
  
let MAX = 100;
  
// function for calculating frequency
function freq(ar,m,n) {
    let even = 0, odd = 0;
  
    for (let i = 0; i < m; ++i)
    {
        for (let j = 0; j < n; ++j)
        {
              
             
            // even and odd
            if ((ar[i][j] % 2) == 0)
                ++even;
            else
                ++odd;
    }
    }
  
    // print Frequency of numbers
    document.write(" Frequency of odd number =" +
                    odd + " <br>");
    document.write(" Frequency of even number = " +
                    even + "<br>");
}
  
// Driver code
  
    let m = 3, n = 3;
  
    let array = [[1, 2, 3], [4, 5, 6], [7, 8, 9]];
  
    freq(array, m, n);

输出：

Frequency of odd number = 5  
 Frequency of even number = 4
