Frequencies of even and odd numbers in a matrix

Given a matrix of order m*n then the task is to find the frequency of even and odd numbers in matrix 

Examples: 

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

Implementation:

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

Time Complexity: O(n*m)
Auxiliary Space: O(1), as no extra space is used

Method: Using bitwise & operator

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

Time Complexity: O(n*m)
Auxiliary Space: O(1), as no extra space is used
